I never saw Beanie Babies in my economics textbooks, yet they were a physical product with limited supply, that people exchanged for sometimes large sums of money on the basis of its rarity and collectible value.

NFTs aren't even that. They're basically a mass-produced print with some unknown artist's signature. And unlike autographed mementos, NFTs require a ridiculous amount of electricity to generate each additional signature.

Were. As in, now they aren't. Because there's not any real value there.

Perhaps this kind of bubble / craze should be in economics textbooks - one that covers social and historic factors of failure. Probably Beanie Babies will be dealt with in the preamble on the section of Cryptocurrency, as a foreshadowing. And after the chapter on the Albanian ponzis and Civil War in 1997.

The reason I expect it'll land in economics textbooks is that the snake oil of the blockchain has provided a very pure marketplace for these bubbles to form, including a complete and visible transaction record. That provides a level of rich data in the context of a natural experiment that researchers normally can only dream about.
