Sorry, but spoken like someone who has no idea how the fashion industry operates.
Seriously though, it’s one thing to not like the superficiality of the fashion market, but to deny that NFTs exploit the same demand (for less-gauche proof of wealth) seems wrong.
Recently I learned folks appraise ‘64 mustangs based on VIN and markings - so they know how close to the “first off the lot” that mustang was. They don’t need a blockchain to do that.
I think there is a valid point to this take - humans don’t need irrefutable cryptographic proof that something has a story attached to it; they just need enough compelling evidence the story attached to an object is true. And the kinds of stories folks value tend to be human stories (this is the crown worn by so and so, this is the finger bone of saint so and so, etc.) which NFTs can’t capture.
You indeed do not need a blockchain - the artworld has been doing it using paper certificates for a long time. But these are conceptually the same as an NFT, just accessible and tradable.
