But you do actually own that cap. Someone can’t take your cap away. An NFT pointing to a central server can be taken away. There is some robustness to IPFS of course. And while it’s true that the player can “mint” new autographed hats, it’s different than the fact that anyone can make duplicate NFTs of what you own. The cost of doing so is much less than getting a busy player to take hours signing hats. This is also why value of such things tends to go up after the player dies. It’s no longer possible to make similar works so the scarcity is locked. Again, not true with an NFT.
