As with any other kind of collectable, scarcity is created artificially. There is a potentially unlimited number of baseball cards. I can print one for myself today. Yet it is the authenticated 1933 Goudey #53 which is worth $4.2 million. NFTs provide this authenticity.
Except that they don't, and still rely on experts to give any kind of authenticity. NFTs are like the serial numbers on dollar bills - if the dollar is genuine, then that serial number is unique, but the serial number itself doesn't prove that the dollar is genuine.
