People don't seem medical services because they want to, they do it when they need them. It is the only industry where there price list might as well be replaced with "we will take as much as you can afford". No one can afford to be stingy with money with health and live of their loved ones on stake. It is very asymmetric situation, so it is clear to me why someone would want to ban for profit hospitals.

I think you’re addressing a different point than the person you responded to. They are asking for a positive argument regarding why healthcare itself should make a profit. That doesn’t imply banning profit, or that doctors aren’t compensated at market value
