I've thought about #2 a lot (well, with less hilarious-in-my-mind iconography), but the issue with becoming fertilizer is human->human diseases. Also if you normalize the behavior, it comes back to bite you during plagues where the crops will become diseased.

Ultimately I land on: there's enough 'gotchas' with decomposing human remains where I think a graveyard will do. Though, I wish the casket wasn't necessary.
