Nostr: control your identity with one key pair, easily switch from app to app. Your data is yours only.

Also Nostr: if your keys get compromised or lost, that data is out of access forever. Just start again from scratch with a new pair.

I think the second point gets hand waved away too easily. For a large part of the population this is a major show stopper. Losing your entire online presence with no way of recovery would be devastating for people, and that needs to be solved. If a site has a solution where users can recover from lost or forgotten passwords, what does Nostr offer in that regard?
