> Healthcare practices that provide necessary care shouldn’t even really be allowed to be for-profit entities if you ask me. The incentives become too perverse as a result.

You don't need to disallow them for necessary care to be provided. You can just have public healthcare programs. That can look like publicly-owned hospitals or regulation that private hospitals must provide certain services under certain conditions if they want to keep operating. Private healthcare then works to provide more than that basic service that fulfills necessary care, to the benefit of the public that can afford more.
