And then more and more providers would opt out of taking Medicare at all, so we would quickly end up back where we started.

		The "just" is doing some heavy lifting there. Clinicians aren't required to participate in Medicare; in fact they have to go through a complex process in order to join. And there's no way that such a mandate could ever pass Congress, or be effectively enforced.
