I mean, if by value, we mean a "good or a service [someone] would be willing to spend USD on", then yes, all the things I mentioned are things that people have spent money on in one way or another, presumably because they felt that they were getting something in return by parting with their money. From an economic perspective, the crypto product incentivized labor of some sort, so it would arguably qualify as "creating value". My reservation for whether to call those products "value" is more along the lines of the argument about whether cigarettes are "creating value" (i.e. if one buys a "feeling" from literal puffs of smoke and punts the costs of externalities onto others, is that a net positive?)
