ELI5:How can people without insurance who are taken to the ER after having a heart, stroke, car accident etc be required to pay their hospital bill when they're unable to consent to any of the services being performed?

I recall going to the ER in college and signeing a form consenting to paying my bill for any services performed. How can people who are unconscious be forced to pay for something they never agreed to. Can't they just say after the fact that they never agreed to anything and would have been happy to have been left dying on the side of the road.

Edit: A lot of answers seem focused on the obligations of doctors and hospitals. What I'm asking about is what are the obligations of the patient. If emergency rooms have to take everyone regardless of ability to pay, why would anyone ever pay for treatment they never consented to?

Because in the absence of contrary information (a medic alert bracelet saying "let me die"), society (and the law) has decided that basic, minimum care to preserve life is the default standard.  So you are therefore liable to pay for the service.
The opposite would to be require consent at all times from injured before doing anything.  Considering that the more serious the injury, the higher the likelihood of not being coherent or awake, a ton of people who would otherwise be save would instead, die.
