"Free market" healthcare assumes that some insurer will sell insurance to someone with cancer. ...
No it doesn't. Where did you get that idea?
That is so elementary that it does not even warrant a serious response. But, I will give you a hint. In the free market of automobiles, if Ford does not produce a pickup truck that meets your needs, you can always by a GMC instead.
And if GMC failed to meet your needs, would you then conclude it wasn't a free market? A free market makes no such assurances.
Come on, Black, you are stretching your point. The basis of a "free market' is that competitors produce lower prices and better quality. There is no insurance company in the US that is competing for cancer and heart disease victims. In short, there is no "free market" in health insurance.
Yeah. If you're saying there will never be a market for selling insurance to people who are already sick, you're right. The concept makes no sense. Health insurance is for people who are currently healthy, to insure themselves in case they get sick. It's not a "golden ticket" that scores you free health care.
