how would you address relays? move everything to tor? can we do some kind of hidden service addresses for nostr too? maybe nip05 should serve as the only anchor to dns and then you can address notes as [email protected]/bookmark (and bookmarks will be listedin .well-known/nostr.json similar to rel...

Agreed. If we have a nip65-like event to point npubs to IPs, As long as you know the ip of one relay, you can find everybody else's IP.

Yes, currently DNS is very centralized (plus names are effectively rented). But we must have some sort of human readable solution for naming (as opposed to memorizing an entire npub, for example), or else it will look like we are taking a step backwards.
