That's a logical fallacy. In this fiat world, we don't really have division of labor. The massive fiat plunder is basically bringing us back to the stone age. You could divide the world right now between people that have a lot of different non-specialized skills (I.e. cavemen) and the people that are basically spoiled brats (i.e. the lemmings). Putting the argument that Nostr doesn't work because it doesn't have diversity is nonsense because we didn't even have true diversity as a civilization.
