It’s more why is the @ in the middle in the first place? I’d like to understand the problem we’re solving so we build the best ux experience

You need some kind of delimiter between the name and the domain. My guess is we just made it like that cause nip-05s work in a similar way to lightning addresses and that’s how lightning addresses are formatted.
The problem nip-05 solves is giving users a human readable unique identifier on nostr. It’s easier to share a nip-05 than an npub.
It can also prove you have access to a domain. For example, if you’re well known and have a personal website and use that for a nip-05, then people will have more confidence that it’s actually you and not someone pretending to be you.
