I suspect the problem with a "Tesla of health care" is that it's so decentralized that there's no way to bring a coherent new product in a market economy. You could potentially build a small self-contained ecosystem-- say, in a metro area or small state-- but it starts to fall apart if your package can't provide any coverage the moment you're out of town and have an emergency. Realistically, only entities the size of a nation state can really provide something meaningful there, because they can have the tools to get buy in.
