All those things could happen but the healthcare provider will mug you once a month.
There has to be SOME point where the constant muggings aren't worth it vs the risk, otherwise they would simply demand all our money, knowing we won't say no with our life on the line.
Agreed and generally insurance would be a value bet between you and the insurance providee with a slight operation overhead. In the US the market is basically circular as the insurance provider also has hands in all related pies so the bet odds are in such awful state that some people take the risk and rely on crazy stuff like gofundme for survival. I'm not an american but this doesn't look like something that can be solved with more market - the odds are just so broken in many cases.
