I totally agree with you, it is important for people to understand that a medical doctor does not really care if you can walk a mile without pain, but it is way too nuanced to track quality of life changes across a large population. We would need to change the insurance landscape and make it easier for other medical practitioners to get insurance money and let it naturally change.
If even a little bit of the insurance money could start funneling into things like physical therapy (actual physical therapy not the BS artists at big hospitals who print you out a sheet of generic exercises) people could see practitioners who actually care about you being functional.
I tore my achilles and saw a string of doctors, podiatrists, physical therapists, chiropractors, etc. before finally finding someone that doesn't take insurance but who had me running again within a few months. He was cheap compared to the amount my insurance was being billed for a chiropractor to try and sell me $500 custom insoles. The money is there it is just being funneled in all the wrong ways.
