If I have cancer and I need to start treatment as soon as possible I’m not going to waste precious time comparing rates of infusion centers, especially given that one may be able to take me in for treatments 2 weeks sooner. That two weeks could make all the difference
If I have a heart attack, stroke, car accident, etc, that incapacitates me, I am simply incapable of shopping around for the best price. I am going to be taken in for emergency care and treated to the point of stabilization (or better, depending on whether I have a guardian who can approve more. Said guardian could theoretically shop around at this point but it is difficult given the potential emotionality involved and danger in moving someone who is critically injured)
Increasing provider supply is certainly a huge part of fixing things, if it’s done correctly. If you merely lower standards you just increase supply with substandard practitioners that overall worsen outcomes
