One of the main concepts in introductory economic classes is that most things that people value are scarce. That's why we pay money for them, unlike air. And money is nothing more than our saved labor, services we have rendered to others in the past. In the market, we merely exchange services.
Healthcare is no different. Doctors and medicine are scarce. That's why we pay for them. The US suffers from an artificially large scarcity due to regulations, but even counties that offer free healthcare face scarcity. In the US, medical care is very expensive because of the artificial shortage caused by regulations and partly because we can afford it. We ration that scare resource though high prices.
