Your analysis is not quite complete. There is a great deal of abuse potential with the current system. For example, a wealthy patient who is severely injured, but not really "hours away from death" becomes a candidate for organ harvesting. A couple of corrupt doctors working with the family who will inherit the estate could easily facilitate a murder.
As an anesthesiologist, I have been asked to be the one to pull the plug in the OR and pronounce the patient dead prior to harvesting. In these situations, the OR team knows nothing about the will of the patient or the character of the family.
I would view that as a serious ethical violation. If what you say is true, then the hospital is negligent regarding it's protocols or lack thereof, or the protocols are not being enforced.
You would have a valid grievance in my humble opinion.
