So a free market in health care is not possible because you can't consider your options and say "no thanks" when you need emergency treatment. Whatever the government does or does not do, you can't really get around the fact that at a moment of crisis health care providers have you in a coercive situation and could charge life changing amounts for care if they were permitted to.
