NFT for authentication... ya, especially into and within virtual worlds. I'm more excited about the possibilities of LN for authentication, sorta how it's used here in SN. The monetary aspect really ads alot to it all.

One good example of NFT is right here, Stacker using `lnurl-auth` is better (waaay better) than most web3 obsolete projects, to verify people with no need of any kind of data. Of course @k00b doesn't put monkeys nor strange creatures to put it in your profile because if you want to buy art, just use...money, IDK, maybe...bitcoin?

I agree with you that NFT have future. I can't be certain in what way but most interesting part for me is the authentication part (login in your website) avoiding useless or important data of yourself.
