Wow, that's frustrating. It's not communist, it's post scarcity! Why on earth would we still have capitalism (i.e. a system for allocating finite resources) when resources are unlimited? Once you can have anything you can imagine by walking up to a machine and telling it what you want, what would you be buying with money?
Communism, in contrast, is a different approach to dealing with finite resources. That is, if all resources were infinite we wouldn't need communism either.
Otherwise the article looks good, but I suspect if we really arrived at post scarcity and all that was forcing us to slog into the office was IP, there would be a revolution in short order.
