The society of Snow Crash is a dystopia, not something we should want to implement.
It's more The Diamond Age than Snow Crash. The "Patchwork" of Yarvin and Land maps pretty neatly to Stephenson's Clades -- micronations as voluntary societies.
I think/hope we will see something similar to voluntary societies in the future. Nation states are too heterogenous to row in the same direction. Stronger ethics are needed
