Dying isn't complex at all. When it's time to die, we should die. It's about a right to life as well as death. If, like you said, death should be natural, then perhaps we should take the medical system completely out of the equation and lay the dying in the woods or on a floating section of ice and let nature take it's course? I really don't want a bunch of folks watching me die. I think it's a rather personal time not a stage play, final act!
