It is true that any system needs initial connection to peers, but not all systems are designed to reach strong consistency in a reliable way. Bitcoin for example can suffer from this, but it only takes one honest connection to get the definitive truth.
DNS has a hierarchy that also allows for the definitive truth even if that is a proof of authority.
A DNS based on a Blockchain especially a merge mined sidechain doesn't suffer from the same problem as Npubs do, because in Npubs you never know when you eventually found the source of truth (the outbox) and even worse, when you don't find it you don't know what went wrong if anything went wrong.
Nostr has Negentropy, which I am proud of suggesting initially to its author, but gossip can only do so much. If you want strong consistency, at least eventual consistency, I am afraid you need to embrace either a Sybil resistant DHT and or a Blockchain, the later has better Sybil resistance and offer key rotation.
However, you are correct in that, if you don't give a fuck about consistency and the stakes are low, the. YOLO who cares.
