> there's no reason to take it all with you

Theres no reason to force people to "donate" without bothering to talk to them or their families even once about it. The only reason is to trick them into donating by not telling them they'll be donating, knowing that a large part of them wouldn't donate if they had a fair choice. I think many people _do_ have strong feelings about their physical integrity and the physical integrity of their loved ones, especially in the case of not even being asked.

A silent, deadhearted, mandatory opt-in would be for me a major reason to immediately opt-out without any chance of reconsideration.
