The greater good of society, to ensure stability. There will, of course, still be certain freedoms, but ultimately the goal is to create an environment in which everyone can be happy, comfortable, and safe.'Should' be? Why?
For the greater good of whom?
Really, aren't we talking a matter of degree here? It seems selfevident that all societies develope a system of government in which individual freedoms are traded for 'stability and safety'. Why do you desire so much protection? Why are you willing to sacrifice personal liberty in the name of this 'protection'? Have you looked at the historical connotation of 'benevolent dictatorships'? Or do you make this up as you go along?
Sure you can. You just can't have the society you envision.
No, you can't. You need civilized rules.
