I just want to point out that the use-case that I was talking about was around music-rights, the one you're discussing is art-works :) but that said,

> If you want to authentify an artistic piece, you can just sign it with a private asymmetric key.

Isn't this exactly what NFT-artwork is though? The difference is that the signature is now in a publicly accessible space, like the ethereum blockchain rather than an email. And you now have the option of selling that artwork forward because, unlike an emailed and signed piece of art, there is only a single NFT.

> NFT is just built on the artificial market for rarity and currencies made of pure energy use... useless.

Every time I've tried to address comments like these, the conversation is less-than-constructive. I'm not sure if it's the backfire effect coming into play, or if there's something wrong with the way I'm presenting my information. Regardless, despite my best efforts it ends the other person saying things like "beanie babies", "cult", or "I don't care", and so I've just stopped trying.
