Sure! The homeless guy is very likely uninsured. They might die in the streets because of this. The billionaire on the other hand would get higher quality healthcare. What would not be happening though, is the billionaire paying for the homeless guy's healthcare.

Now of course, a consequence of that is the homeless man dying. Ethically, this is an incredibly shitty system. THAT'S why we need single payer universal healthcare. However, a consequence of that would be the rich paying for the poor people's healthcare.

Yeah I didn’t comment on the “person A paying for person B” technicality because that’s always part of the deal. It happens with private insurance too. If the lowest paid worker at a company is healthy, and the billionaire CEO has a multitude of health problems, then if they’re using the same company insurance the poor person is paying for the rich person. It doesn’t matter that they’re paying the same premiums — the healthy poor person is getting less out than they paid in, and the sick rich person is getting more out than they paid in.
