I think the immediate value of NFTs lies in industries where you need to keep the producer honest to protect against artificial scarcity. For example, what stops baseball card printers from re-printing "rare" cards? And how do we know they're not hoarding some of the best cards for a few years, then selling them individually? I could see NFTs being demanded in situations like this to force producers to create digital…
NFTs are not useful for securing anything in the real world because there is no way to verify that the thing in the real world is uniquely connected to the NFT.
This way you have the physical card to display, and have the NFT as a proof of authenticity and ownership.
