So if there is nobody willing to be a doctor for the pay rate the govt is offering, what happens? Does your "right" to healthcare extend to literal slavery?

I'm being a bit hyperbolic only to make the point... I don't think anyone's "rights" should include forced labor of anyone else. So certain things, even food cannot be a right... I would think that public lands and a right to hunt/gather or even some level cooperative gardening/farming might be okay as a middle ground though.
