However NFTs were trying to assign value to the receipt for the Gretzky shirt.
Well no, in my example the shirt is the image and the signature on it is the NFT bit. Physically, it's just a bit of ink, but the shirt itself is no different than one you can go pickup at the store.
In your example what happens if the shirt is sold to someone else? In the NFT case the signature changes.
The shirt analogy doesn't work well, but
NFTs are great for transferable tickets.
