I'm not really convinced that people thought there was "anything else", it's just that people thought that the entry on the ledger was going to increase in value, even from some of the stupifying initial values.
I own several NFTs that are important to me, and they're worth every penny I paid. I never had any illusions that I owned anything other than a historical footnote; I think that this sort of ownership is meaningful and important.
It's much more realistic to me than "buying a song" from one of the corporate music distributors. "Owning" a song seems to be much more of a misunderstanding of how data works in a digital world than owning an entry in a ledger.

The problem with the NFTs is that you don't actually own the art they represent and have zero copyright claim to them. In the absolute very best of cases, if you squint hard enough, you could see them as roughly equivalent to the signature of the original creator of the work of art and you're effectively buying a signed digital print of the work. In the worst and more common cases, you're buying nothing at all except a hash on a blockchain.
