For some people, it's not connection between NFT/token with object. NFT is proof that you're legitimate owner of the object, although it has no legal power and many people don't care about it.
And that's another fundamental problem with NFTs 
You're supposed to download every art you purchase. You shouldn't leave your products on third parties. The whole NFT thing works as long as there's at least one NFT marketplace. An analogy with bitcoin is to always have at least one centralized exchange.
This reminded me of another fundamental problem with NFTs, both the owner and anybody else in the world can also download the "art". In fact someone has already done that and shared the whole database of "art" with the world like piratebay called The NFT Bay with 19 terabytes of data!
