Except NFTs aren't artificially scarce, I'm not sure why people claim this. You can fork these chains just like how Bitcoin Cash was forked from Bitcoin.
But Bitcoin Cash has much lower unit value than Bitcoin, indicating people see them as different things. That seems to weigh heavily against your argument, rather than supporting it.
So if I sell an NFT how many third party sales forked off of how many subsequent sales should I consider official or not? Also, during the split, they were worth about the same, and you could sell one for the other on many exchanges. Is this what NFTs are supposed to be?
