There are dozens of communes out there that seem to work fine. I'm not particularly pro-commune but it is very disingenuous just shotgunning all of them with your expectations of failure when many communes have been running for 30+ years, and Cuba has been doing about as well as the capitalist countries of latin america even through all the sanctions that made that government unable to trade with almost any other.
Viewing post in Is this a political satire?
As I said people can choose to form a collective collony or group and make it work as long as it is volentary. But of course then it would be Capitalism and not Socialism and it does not scale well.
As far as Socialist or Communist countries they always result in misery for the people and collapse. I oppose sactions on whole countries as they harm the people and give the Dictators a scape goat.
