@js290 communist at the commune level is not communism. If you voluntarily share your goods with others (you are not forced to live in the commune or forced to follow it rules) then it isnt communism. Just because you live in a communal fashion it isnt communism. The second you make it voluntary to contribute it simply isnt communism, almost by definition.
By that logic everyone who is in a marriage (without a pre-nup) is a communist because they live in a commune of 2.
