If everyone in the US was in the same risk pool, and we had some good rules in place to prevent insurance company fuckery like denying legitimate claims based on spurious accusations that are difficult to prove wrong or preexisting conditions, then it probably wouldn't matter that it was private.

At least make it a gov-owned private company like the fed if people are worried about executive dexterity.
