The thing I really enjoy about non-fungible tokens (NFTs) and "smart contracts" more broadly is that there's no way to get them to point to information or objects outside the blockchain without introducing a trusted third party, the whole thing you set up a blockchain to avoid.
Yeah. Figuring out how to add PGP's problems to the blockchain is a real chocolate-and-peanut-butter achievement

I agree with you in principle. Most of the NFT platforms just point to a web URL and don't bother. In practice you are right. But with static assets, if you have a trusted public key of the author + hash of the artwork, that's all you need to have on the chain for it to "work"

I understand, but the "trusted public key" part is where the entire problem lies, if the rest of your project is all about a trustless distributed network. At that point you have given up (philosophically speaking) and might as well use existing trusted systems that work better.
