Oh, sorry, I wasn't intending to argue against your main point. For the most part, I agree with you.
What I don't agree with is that the value of NFTs (as a technology) is dubious. Instead I think it's overstated.
In the same vein as "LLMs can write Python", NFTs provide ownership information. Regardless of what some asshat pays for a picture of a monkey, the underlying technology still has merit.
I'm a furry, so I'm going to use an example that is familiar to me. Apologies if you dislike furries. Also note that, as far as I am aware, the general opinion of furries is strongly against blockchain.
So, some setup:
Here's how NFTs would actually be useful:
Whenever an artist draws some art, they mint an NFT and transfer it to the character's owner. Now that owner can prove to whatever roleplay websites that they officially have permission from the artist. The roleplay websites would need to allowlist artists for this to be effective.
You could (partially) solve this with PGP or some other non-blockchain cryptographic tool. What NFTs offer above this is that there is only one current owner. That makes it possible to safely transfer ownership of a character to someone new.
