Earlier quoted context omitted.
There is another critical difference: The person creating the NFT is, in theory, the artist who as a claim to authorship of the work.
True, its more like an artist assigned numbers to all their works and sold the right to put your name on a website next to that number. Maybe for some artists that means something like getting a shoutout on their Patreon but totally worthless in abstract.
Sure. But if we create a community of art collectors for whom this sort of shoutout does mean something, then these things start to have concrete value - because you can sell yours to someone else. This means artists now can earn money by selling such intangible works, which strikes me as unequivocally a good thing.
