... if Bluesky users owned their private key.

I think the lack of owner's custody of the private key in bluesky is more the result of a convenience design than of a technical limitation. If the user is expected to manage the private key, you might end up with something similar in complexity to Nostr. But it might still be possible if you're running your own PDS.

You don’t need to run your own PDS, the key that matters is the rotation key for plc.directory.
