It’s important to note that the “thing” you “own” is the receipt, not the art.

The NFT is not the art and doesn’t contain the art, it’s (in the vast majority of cases) just a link to the art. You have no ownership or claim to the art itself.

I think that's a bit reductionist, in the same sense that you don't "own" land just because you only hold the deed.

Unlike some things in the cryptocurrency world, NFTs are not meant to replace the legal system and property rights.

The deed is backed by an actual legal contract and enforced by the government.

An NFT transfers no legal authority or rights to the thing it points to. The only thing you own is the NFT which is some JSON and a URL. You don’t own what is at the URL.
