Also its just factually incorrect. That argument doesnt work for healthcare for two reasons:
it is a necessary service. People who need it don't have a choice.
Practically nobody actually buys their own health insurance; they get it as a "benefit" from their employer who chooses the provider and available plans... and guess what? Their employer is also a company whose only goal is to maximize profits. Yes there is an open marketplace for health insurance but be honest have you actually heard of anyone actually using it?
So basically its not really a free market, its a cartel and they can charge whatever the fuck they want.
I remember his memoir in 93 when he discussed the ethics of defending one monarchy from another, it was very insightful but it began to ring hollow by the tenth war he fought against Bowser.
