As I already stated, this is not true. Nobody can stop an author from minting two different blockchain NFTs pointing to the same content, there's no difference between that and "double spending" a digital signature NFT. At the end of the day, the only thing the NFT does is prove "the author authorized this verbal statement of ownership", a digitally signed text file does exactly the same thing.
You are correct double spend is not a problem with NFT because they piggy back on crypto layers.
However double spend is a problem with just digital signatures that “retroactively obsoleted” NFTs.
Since there are multiple people commenting and steering the thread in different directions I feel this is being filibustered. So ill stop replying. Im exhausted!
