I'm a fan of opt-out organ donors. Unless you have strong feelings (possibly religious beliefs), there's no reason to take it all with you.
Porn, on the other hand, has very few externalities.

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.
I would have said a shortage of donor organs would be a reason to force this? Maybe not an acceptable reason to you, but still a fairly strong reason.
And if you think it's an overblown fear, consider what happened to the guy they tried to autopsy in South America about a year ago: he woke up on the table.
I am not saying that it is likely to happen, but since your benefit from this is Nothing, it just has to be teoretically possible for it to give you an advantage.
