The one weakness of Nostr I can see is the domain names/DNS/ICANN system. It's not that it is likely that a crack down on Nostr traffic comes via domain name registrars, but it's just that it's a centralized system that requires some approved actors. One way to get around its ip-host mapping and self-signed SSLs, but that seems like it's opening itself up four a lot of vulnerabilities.
A trusted npub signing an SSL for a specific ip-host pair could be an interesting thing to ponder.
