Agree. A bit worse than changing your email/phone, but fixable. Web-of trust can be reclaimed.
Lost/hacked nsec would work like this:
✅create new key pair;
✅reach out to your most *popular* followers;
✅they use their established trust to verify your new npub. ✅Word spreads fast to their WOT…. on and on
With walled garden central control you would have to rely on central authority to reclaim, with NOSTR your fellow users who have built their own trust can assist. This fix strengthens as network grows.
