Well, this has been explained to you and Michael numerous times over the years, there is a difference between microeconomics and macroeconomics.
Yes, there are some differences. But usually these differences are not important.
There is an exception. For nonsensical economic theories, which make claims about macroeconomics, it is extremely important to emphasize that
there is a difference between microeconomics and macroeconomics because this allows to sell the sheeple nonsensical things, which even the sheeple would be able to identify as complete nonsense if there would be no excuse that macroeconomics is something
completely different.
You cannot apply kitchen table economics to the macroeconomics of a nation and remain credible or reliable.
Of course, for most problems you can. Of course, because the conclusions are usually different from Keynesian pseudoscience and uncomfortable for politicians, you will be faced with the usual reaction of losers in discussions - you will be attacked ad hominem. This will be named you will not "remain credible or reliable".
There is nothing wrong with fiat currencies, every currency is a fiat currency even if the currency is backed by gold or some other commodity and none are. And the problems with commodity backed currencies have been discussed ad nauseum in this forum over the years and are why no nation on the face of the planet uses a commodity to back its currency today. There is no magic in commodity backed currencies as you and others seem to believe.
There is something wrong with fiat currencies, namely that it needs force to obtain a value. Commodity-backed currencies do not have this problem, so that they appear on free markets in a natural way.
There is, of course, a simple reason why no state on this planet is using today a commodity-backed currency. First of all, because using the printing press to obtain money is very comfortable for the politicians.
There is a second one - US leadership. Any reliable commodity-backed currency would be preferable as a reserve currency in comparison with any fiat currency, simply because it does not loose value by inflation. So, the development of a gold-backed currency would endanger the dollar, thus, to do this you have to face the danger of having the US as an enemy. This would be fatal for almost every state on Earth, except the largest ones, Russia and China. Above have avoided, as far as possible, open confrontations with the US. But if the situation becomes more serious, and it does no longer matter for them to have the US as an open enemy, they can start to use a commodity-backed currency.
Above states increase during the last years the gold part of their reserves, which can be considered as a preparation for this. Other states, like Germany, try to get back their gold reserves from the US, but get only small parts of it. Looks like above are preparing themself for this, as well as for a future where they are no longer good friends. So, there are reasons to think that gold has a future as a backing of some future currencies.
Two, there is nothing wrong with the fractional banking system. It’s how banks have always worked. Fractional banking predates the founding of the US.
Fractional banking is a variant of cheating which usually works, if one does not exeggerate. It is the danger of using a commodity-backed currency instead of the commodity itself, which makes this cheating possible.
There is nothing wrong with a well regulated fractional banking system, which is what we have. In fact, a fractional banking system is integral to a well-functioning modern economy where capital is efficiently redeployed from surplus to where it is needed. It creates jobs and products.
No. Cheating does not create anything, it is a redistribution. It "creates" income for the cheater, taking it away from others.
There may be some special situations where printing money is useful. The particular example is an economic crisis in a state where trade unions have reached a lot of power so that they can forbid a decrease of wages in the whole industry - and not only in particular firms which have signed a contract with the particular trade union. Now, it may be necessary to decrease wages, but the trade union may be not interested and block this. The result would be that a lot of small firms go bancrypt, while the big firms, where the trade unions are strong, survive - an outcome the trade unions are interested.
In this scenario, printing money causes inflation and effectively decreases wages. Which prevents the worst outcomes of this situation.
Similarly, printing money can prevent the worst outcomes of minimal wages - to decrease them would be impossible in a democratic state, but to print money, so that they effectively decrease, and selling this to the sheeple as you do, is possible.
Three, there is no evidence to even suspect banks or the US government are overleveraged, absolutely none. As has been pointed out to you instead of falling in value as you predicted for years now, the dollar is rising in value and is stronger than it has been in many decades.
This is only a relative point. We live in a world where this method of cheating is used in all states. The states who print more money will have higher inflation. The states who are trusted to cheat less can print more money without causing too much inflation. So, for example, other states may hold some Swiss francs as part of its reserve currencies, but hardly Simbabwe dollars. But above things are cheap paper, and this difference in trust gives the Swiss central bank an income.
And, of course, in a world very close to a big war people will tend to consider the currencies of the most powerful military powers - the likely winners of the war - as more reliable. This is part of the explanation why the US becomes more and more aggressive and spends a lot of money in wars which lead only to destabilization.
But if the world switches from the unipolar to the multipolar world order, the role of the dollar as the world reserve currency will be lost. And this means, a lot of dollars now used by the central banks around the world go back to the US. If this would happen at one day, this would cause a heavy economic crisis for the US. But nor Russia nor China are interested in such a crisis, because it would hurt them too. They prefer to do this slowly. The way is to allow in bilateral trade to use the currencies of above states, so that above states can hold some reserves not in dollar, but in the currency of this other state. Economically meaningful for above sides, because it is diversification of the own reserves, and because it is what one needs to support these trades. But certainly not optimal for the US. If this becomes the rule, dollar reserves will be hold only by the trade partners of the US, and only to support this trade. For everything else, gold, silver, and other commodities will be preferred.
Greece’s debt problems could be easily solved, its governance problems which caused its debt are an entirely different matter.
No, there is no easy solution for debt problems - except for states with an own fiat currency, and with debts nominated in this currency. In this case, the state can simply print the money to pay the debt. This leads to inflation, but so what? This is a problem of those who have to use the currency - thus, for the citizens of the state - but not for the state.
But Greece has no own currecy, thus, the cheap solution is not available. Or you have to print a lot of Euro, with inflation in the whole Euroland, which is nothing Germany is interested in, or the debt remains big.
The other point is that Germany want to have Greece with a big debt. This allows it to rule over Greece.
