This is not true. Emergency rooms are required to take you in and stabilize your situation even if you can't pay. Everything else is not available if you can't pay.

Think of something like cancer, which an emergency room can't treat since it develops over time. You will indeed be left to die on the streets if you don't have the money or coverage from somewhere.

Yes, because that's the law. Then they hand you an exorbitant bill on the way out, which you can't pay. Then you get hounded by collections. Then your credit score tanks. etc. etc. etc.

Not everything is a direct line, the end result is the same.
