Why do so many here seem to be so proud of their lack of understanding of the value of NFTs?
If you have an NFT, you get to do things others cannot. That's the value right there. At the very least, holding an NFT gives you the ability to transfer it to someone else and make them the holder. Anyone can confirm that you did in fact transfer it and made the other person the holder.
In addition, you potentially get access to other benefits, such as acceptance of some alternate meaning in the NFT social circle as well as potential benefits in software written that respects the NFT.
What seems to have taken off most is that the NFT social circle will accept ownership of some linked item within the NFTs data. They see the NFT record as a register of provenance that they're willing to recognize.
Do NFTs signal legal ownership? I imagine we're going to find out that it probably depends. But even where they don't, they certainly signify something akin to ownership or possession. And that ownership of scarce goods is precisely something that is valued by certain communities, especially the art trade community.
That you can mint your own NFT with the same data, or that a link in an NFT stops working don't really change the nature of the kind of ownership. What NFTs offer sort of mimics the 'realness' of a piece of art. I can make a picture of the Mona Lisa too, but no one will respect that picture as the real Mona Lisa. While you might lose out on the pretty physical object, you gain in cryptographic provability and potential software integration
