Earlier quoted context omitted.
At least in the tulip case, they actually had some minor value. You owned a pretty flower. You could also make the case for crypto money, I guess. Any person with common sense and basic technical understanding could tell you NFTs were an incredibly dumb and useless idea from the very start. All you “own” is an entry on some ledger, which doesn’t inherently give you ownership over anything else.
Exact same argument for crypto though. It is all just supply demand. BTC has much more demand currently and likely more sustainably. Alt coins are just less popular. It is all just supply vs demand.
NFTs use the same machinery but the premise is that you own something else, e.g. an image (or real estate!) but nothing on-chain actually grants that ownership. To the extent real ownership exists at all, it lives entirely off-chain, e.g. in a legal contract (that would hold with or without the blockchain).
I am not a fan of crypto either way but NFTs are just ridiculous.
