At the core of the concept of buying stuff, is, I buy something from you, I then own it. If the NFT craze can't satisfy that one criteria, then anyone who hands money over for them is being scammed.
I can see this developing at some point, whereby there is a physical world way you can scan an item and see that it has a unique code and therefore is definitely the original.

To be fair: You own something you own a token that is represented by a thumbnail image (kind of like a virtual dollar bill but without the image of a past leader of your country) ... however it'd be nice if that token represented something more... like rights to art. If they don't give rights to the art then it's perhaps even hard to call it NFT ART
