You cannot own it. What matters is the part that can accrue economic value. That’s the token.
Seriously you proven the point. You bid on token that is supposed to represent something that it actually isn’t tied to at all. So each token is really just a commodity, that suckers think is rare, but since the tokens aren’t actually tied to any object (virtual or physical) through any meaningful access control to enforce exclusivity, the tokens are actually indistinguishable hexcodes. At most it’s license plates rather than cars, but more like trading cards of license plates, since the NFT doesn’t enforce access controls, but the state DMVs — that have nothing to do with the NFTs — do.
Re NFT: what we’re seeing now is only the beginning. Is there hype? Sure. Is there a deeper underlying point though? You bet. NFT access control will come. But it’s not that crucial of a point as you seem to believe.
