It is doable but one thing is, many of us don't like to mix IRL ID with digital ID so, I will definitely be the one who skip dating apps on Nostr if they came into existence.

I don't like to show real me on the internet. I don't mind if everyone knows which part of the world I live in but I wouldn't like to pinpoint my exact location.

People do all crazy shit anyway and Nostr dating will be one of them for sure.
