If I've understood the Foley case in particular, the reason they are charging him 1,500 a day is because he says that his previous government issued long term care plan ended up with him getting food poisoned and injuries from the care provided at home, and they refuse to grant him any agency over his own care, therefore he is refusing to leave the hospital. So you dont exactly seem to get a freedom to choose when it comes to how you'll live with fatal conditions.
