But that makes the NFT less valuable. If the content at the url changes without the hash you still have a useful NFT. With the hash, your NFT is burned when it changes.

As a buyer I would want that one less. In the fraud case adding the hash damages only me.

Without a hash you just simply trust the issuer unconditionally? And you prefer this trust over a cryptographic guarantee the content, and thus the meaning, of the NFT won't change?

This whole NFT really is inscrutable.

I see what you mean. By producing the content you can verify the cryptographic hash. Okay, I misunderstood previously.

Yes, that is meaningful. What usually happens in the case is you just as well use a content-addressing system like ipfs for the URI.

Yes, you could just as well store just the hash. Very reasonable.
