It's actually simpler than that. It's just an entry in a database with your name attached to it. It's like an autograph. Why do database entries have value? Well, usually because there are processes attached to them. Often it is as simple as having a court enforce the process. I don't know why but the whole cryptocurrency space feels like a philosophical parody of the real world. Money without people. Contracts witho…
They have value because people agree they have value. Trusted third parties (like courts) help people come to that agreement, by providing transparent, objective processes to settle legitimacy and ownership disputes (in the happy case, in the not-happy case they use physical force to reach agreement). Personally I don't understand the controversy, blockchains are a different kind of trusted third party that also help…
For example, let's say you have an NFT that represents something tangible (and not just some link to an image download). What happens if the owner of the NFT dies without setting up a way to transfer their NTSs? What if multiple, seemingly valid NFTs point to the same object? What if the NFT was never truly valid in the first place? What if an NFT is stolen?
In all of these situations, a third party (like a court) would have no actual power to fix anything within the NFT space. A hard fork is theoretically possible, but that becomes impractical to do every time someone has an NFT dispute. The only option is to just declare an NFT invalid. But if you have some third party that controls the validity of NFTs, then you might as well cut out the NFTs and just rely on the third party.
