NFT's fit into the collector mindset. An NFT owner can brag to his friends that he "owns" a unique asset. To some extent, I collect cameras and lenses. I do, however, expect to make photographs with each of them. There are others, however, seeking to buy cameras and lenses in unopened boxes and never opening the boxes. There are people with beautiful Leicas sitting in a shelf which never get used. Are cameras with low serial numbers better than those with higher numbers? There are people who assign value to objects independent of the underlying object. To these people there is value in NFT's.
To me, blockchain is a neat technology with little practical usefulness. I remember Kodak's effort several years ago to start a photographic blockchain market. I have seen many other efforts to employ blockchain, none of which panned out. It is useful for cryptocurrencies, but I don't invest in products I don't understand on a fundamental level.
On the other hand, if anyone is interested in buying an NFT of this post, I am offering it now for only $75 ,000. I'm sure its value will skyrocket when this thread is somehow resurrected a few years down the road.
