What is the difference between a painting by Leonardo, and an exact copy by a very skilled forger and Artist? “Nothing”. Except, that we can prove Leonardo painted it as we have the history of ownership. The fact the jpeg isn’t unique isn’t the problem. It’s who minted the NFT. If you know it’s the artist, then only that “copy” is the real one. It’s all bullshit I know but there is an approximation of the above question.
