Problem is that the only way to get your idea to happen is to ban health insurance. I am not hearing anybody wanting this, I haven't even heard you say this directly. So banning health insurance is probably never going to happen, and moving to a universal healthcare system is a lot more doable. Second, 60 years ago, medical technology wasn't nearly as advanced or expensive, there was very little obesity, people lived only to their 60s which reduced end-of-life expenses. Today, we have expensive cancer treatments, expensive drugs, years of end-of-life care for 80 year old's, etc. In your perfect era of no insurance, health insurance arose because healthcare emergencies were often bankrupting people, and they wanted financial security when they got sick and get medical treatment even if it was expensive.
