It seems like the person you're responding to is raising a legitimate criticism of NFTs, or at least, criticism of the touted benefits of them: an NFT provides absolutely no value to its owner unless there's some kind of enforcement of the "property" rights it suggests. If I own an NFT of a JPEG, there's nothing to stop anyone else from simply right-click-downloading that JPEG and hosting it somewhere else. At that point, my NFT is just me shouting "dibs!" to a room full of people who don't care.

That's the entire point of a blockchain. It's valuable because other people agree that it is. Of course, the actual JPEG can be copied, but that doesn't mean your blockchain ownership of it does. You are kind of shouting dibs, but the difference is that a lot of people care. And as long as someone cares enough to pay you money for your dibs, then it has value.

Or how about it was a genuine question and you don't have to be rude. No wonder crypto gets a bad rap.
