This is kind of what Hanson is angling at. As I understand it, his thesis is that outside of obvious emergency stuff like infections, tumors, broken bones and such most health impact comes from lifestyle variables such as diet, physical activity, level of stress and quality of sleep. This is not traditionally understood as "medicine" (i.e. something doctors prescribe). But when people have easy access to medicine, they will be compelled to go to doctors more and doctors have an incentive to prescribe more treatments than necessary to maintain the prestige of their profession. So in the end many of these treatments will have either negligible effect on health or even be actively harmful.

I had an intermittent chronic pain issue for a few months this year that went untreated because of covid backlogs (UK). It stopped before they had a chance to figure out the issue. Even assuming it never comes back again, and I am now "healthy" again - the impact this had on quality of life was stunning to me, as someone who had never experienced this before. Pain, anxiety, frustration - I would have paid good money to get it treated earlier, and I don't know what I would have done if I was poor + living in the US.

I'm not sure if this answers your question - but in general I don't believe health care should just be about preventing death.

Yes exactly, it's written like "when you have insurance you take more medicine which is not healthier" Insurance is normally not for small stuff but big failures...that's why you need insurance (and only for that)..because it's ~impossible to pay for it.
