Earlier quoted context omitted.
There can be as many NFTs for the same thing as anyone feels like producing. We could all mint a different Mona Lisa NFT.
Well yes. But anyone can make a reproduction of a Warhol print. But there is a chain of custody that adds value. I'd like to reiterate that I think the value in a Warhol print is also stupid. It's less stupid than NFTs but the point I'm trying to make (apparently unsuccesfully) is that these differences are matters of degree rather than type. We humans have a multitude of ways to invent value that is built on sand.
Minting an NFT is trivial, you can do it with the press of a button, at scale. You could mint an NFT for every single item in the Library of Congress with a for-loop, if you could pay the transaction fees.
