If you’re moving around between servers it means that each server has to validate the users. The matrix solution was to add identity servers that tell the server you’re logging into who you are. I imagine something similar would be necessary to hop servers on nostr and bluesky. Its possible the connected servers share user identities but that has its own array of problems.
I don’t know how the matrix model works to be honest, but I think it’s a totally different use case.
