There's nothing preventing it. It wouldn't be the original however, and in this scenario that's all that matters.
And As seen here, even the "rich trolling" potential is practically impossible to enforce since we run into the idea of "piracy" (in the loosest form of quotes you can imagine). A problem even billion dollar media empires can't fully enforce. Is there something here I'm missing?

on a side note: while memes like nyan cat make sense, I find it very ethically dubious to "own" what's essentially a personal memory of a real family. But I guess if it's the family themselves that sold it, the consentual factors are already in place.
You'd have to own the SD card to own the 'original'. But who really cares? I don't understand NFTs, I just don't understand the value.
