The fact that someone can screenshot something does not make deletion not real. Deletion is still valuable for many threat models and day-to-day situations humans run into.

As someone working on a p2p app that has done a lot of user research, I see it as a really good sign when a federated/p2p systems prioritize deletion, because I know based on my own research that it's something users care about and ask for.

100% agree with you. You can allow the illusion of a delete, and also allow messages to be signed using a keypair. When you build the merkle tree you stop linking to the deleted post and link to the next best non-deleted post.

BUT, if the content is already out there in a distributed system then you have to expect all of the nodes to respect your delete and not optimize for it.
