Good old American Exceptionalism.

The US' healthcare model is not unique, and almost no countries have zero-cost-to-consumer healthcare systems (and none of them are free -- they're just paid by taxpayers instead of consumers). "Free" healthcare is the exception rather than some kind of international norm you incorrectly make it out to be.

The first step to reforming US healthcare is actually understanding it, and understanding some international designs. Lying about it doesn't help.

People wouldn't be externalities if healthcare costs money. Next thing you know you would have to pay attention to the environment or god forbid the food. It would eat away the budget for overthrowing countries and bombing children. Watch them elect a democrat to do the bombing next round and a new republican after that. It sounds like a joke but it isn't funny.
