The more important question and the question you like to avoid is how would your libertarian vision of nirvana make things better? Mistakes happen. That's why we have regulation. In order to minimize mistakes we set up processes (i.e. regulations) to prevent mistakes. That's the whole Six Sigma thingy. The problem with our current healthcare system is the insufficient use of best practices and processes. https://en.wikipedia.org/wiki/Six_SigmaAs an aside, did I mention the conversation I had with a medical student a couple months back? So, a patient goes to see his doctor for a 'kink in the neck'. One (unnecessary) simple spinal decompressive laminectomy later and he's paraplegic and expected to die before the end of the year. Surgical notes: Patient entered with neck pain. Patient existed paraplegic. That is all that was written.
I wonder, do you think he'll show up as a medical error related death or just a death due to natural causes?
And sometimes, even with the best practices, outcomes are not predictable because there are risks and we don't have crystal balls. Even Libertarians don't have crystal balls Michael.
