With all due respect, your take is naive: just because you need a team doesn't mean some members aren't more essential than others.

You can, in theory, have an Oncologist handle your cancer without a nurse; you can't have it the other way around. That makes the former more essential.

Unless you can afford your own doctor, I'm afraid you ate being naive. The reality of care for the lot of us that we depend on the system as a whole working, not individual professionals. If the nurses strike, hospitals shutter. By the way, as an oncology researcher, doctors are vastly overrated anyway. Their main contribution is signing documents. It is my officious goal to make them obsolete.
