It's only verification if there's a reliable verification process to get one. Now, it's just address association with an npub.
How do you reliably verify anyone? You’d have to know them and do it in person, or via some other already verified channel.
I need to see your driver's license, social security number, and 3 pieces of mail sir. 🤣
That's a very narrow view of what verification means. Nostr already has a process to verify your Mastodon github, and Twitter accounts. The process of linking your nostr profile to your external accounts is a form of identity verification that could conceivably be used to verify identity for a NIP-05 address.
