.Philosophically, I'm a libertarian , but modern health care is one of those unique situations from a macroeconomic standpoint in which maximum benefit can not be achieved by a free market
You don't have a choice. The laws of the market are inescapable regardless of the systems it resides in be it capitalist, socialist, quasi-socialist, etc. All economies are trying to utilize scarce resources that have other uses - money, materials, time, personnel. Individuals will adjust their resources and efforts to maximize their returns or personal utility regardless of the economic construct in which they reside.
Either the free market will ration your care or mandated caps will. Socialized medicine will throttle the treatment you can and will receive irrespective of emergent/urgent status. Only you know what is best for your circumstances and how you want to approach those circumstances. It's these micro decisions that affect the macro decisions of the free market and inform producers of goods and services within a free market where to best allocate their resources or face elimination by competitors or loss of revenue by disappearing consumers. Dollars are forced to be efficient and the race to keep customers happy and provide services reduces the cost of delivery of these goods and services thereby increasing the standard of living for everyone.
Don't equate the free market with no regulation. Every market has underlying regulations even if they are informal. Before contracts, tort, and patent law, there were handshakes and physical consequences for breaking agreements. The free market depends on limited regulations to quantify the cost and efficiency of the underlying mechanisms that help industry grow. The problem is when regulations become so overriding and burdensome they begin to impede competition and dictate the decisions that individuals and business can make on how to allocate their time and resources.
Healthcare is replete with inefficiencies and crony capitalism. There is no single payer without reform - it will wither on the vine and those with more resources (the 10 and 1 percent everyone hates) will pay for private insurance or take medical holidays to countries that provide the same quality of medical service for less cost to the private payer.
You can't compare European or Canadian healthcare models to US healthcare models because the underlying cost is different and models that may work in Europe may not work here because of the differences between markets and their underlying support systems (educational costs, immigration rates, social culture, political climate, cost of living, population density, etc.)
