[mothballed]

The train of thought didn't die with Thoreau. It lived on in the minds of those such as Murray Rothbard, and to the extent as it applies to universal healthcare, also known fringe character (and nobel economist) Milton Friedman. Of course Locke himself (a major inspiration for the US constitution, which very narrowly constrains what the federal government can spend money on), I suppose too old as he's the oldest of all of them, only justified taxes so far as they allowed the government to enforce negative rights, that is rights for one person not to molest another rather than positive rights like an entitlement to get something from another such as care.

>your thought is that we have artificial scarcity on medical care because we don't license doctors we could

Really all the above. Probably even more so due to stuff like the intertwining of the insurance and pharmaceutical and medical industries with regulatory apparatus creating all the worst regulatory capture incentives to rent-seek patients with the free market destroyed.
