I understand and agree to a point. Post-mortem payments to estates are cool; it will encourage more people to be organ donors. Not to keen on just deregulating the whole thing, though; I'd be worried about people getting kidnapped and killed for their $20k kidneys.
Potentially not cool. If your hostile ex-wife is your only available next of kin, and has to decide if the plug should be pulled, do you want her to have an extra reason to off you?
I have not checked off to be an organ donor. I do not want to be in a hospital just when some vip needs my heart
