well imagine if you decided to put Nostr events on blossom, or better yet on S3-like object store.. that is what Pubky homeservers are, http servers with simple API (PUT,GET,DELETE + cursor pagination) that you can sign in yo with your ed25519 key once and then have a session with the homeserver as long as you can keep it, giving us plenty of room to secure that rarely used root key. the problem here is, you can't use that ed25519 key and homeserver as the root of identity and still call it Nostr. If you can still call it Nostr, then so be it we are Nostr I guess.
