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:

• I have a character. I pay artists to draw art of my character.
• There is a… subgroup among furries that do not get art of their own, and instead use other people’s art as avatars/profile pictures for erotic roleplay.
• I would prefer that I am the only one using my character’s art as profile pictures (erotically or not.)
• Some furries sell their characters and associated art to other furries.

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.
