The thousands of stolen artworks from DeviantArt being turned into NFTs beg to differ.
Can't imagine why not. Can't at all. Nope.
The NFT is the hyperlink, not what it links to.
The point of the NFT technology is to keep record of who a notary was. "So and so said this link is authentic, per their own definition of authentic." Whether that notary is important is for humans to decide. A counterfeiter can be the notary, and if people believe in them, then they create some value. Just as some art counterfeits have their own intrinsic value for whatever reason.
