> Sure, people can copy and paste a JPEG, but they can’t copy the title. Just like driving a friends car doesn’t make you the owner.
This is exactly why NFTs are different to a car title. If someone tries to use your car (the car which you have the title to) without your permission, then the police can intervene. (They often won't, but that's the principle.) In theory at least, they have no right to make use of that object.
If I own the NFT for a JPEG, there's nothing I can do to stop someone copying it, as you say. Not even an ineffective or theoretical method. That's just not part of the rights associated with an NFT to begin with.
In fact it's worse than that. The JPEG (or the image it represents) can still have copyright that someone can own and sell on independently of the NFT. That copyright is the actual analogue of a car title (though enforcement by the police is even less likely). You could have a NFT of a JPEG but not be allowed, in theory, to have a copy the JPEG itself!
