I mean first of all art is subjective, the points they use to criticize can be easily applied to modern art. For me most of modern art is crap but it has value because people believe in its value simple as that. Even currency is just a paper but it has value because people believe in its value.
But does all of the NFT users believe in or understand about the value of NFT? NFT may be condensed with a lot of buzzwords, and the idea of digital scarcity may become questionable. Though I'd also think that NFT has a lot of potentials, the ideas are there, but the concept of it, in general, may still need room to grow, especially if people want to truly achieve scarcity and ownership. Like how the buyer/collector know the art they going to buy is truly from the real artist, not just some random art copything theft.
