Communism only in the sense that the need for mobility/a nomadic lifestyle means that private property exists only insofar as you can carry it with you. It doesn't work in settled agricultural societies because once a person becomes attached to a specific piece of land as is necessary in agriculture, other types of private property become possible and personal incentives begin to diverge such that the only way to achieve or maintain communism ends up being through coercion.

It is significantly easier to establish communism in a small community, where you can see the people daily that you consider part of your tribe, than a national communism where the work you put in benefits someone on the far side of the country that you've never met, and may consider them as part of your "tribe" on an intellectual level, but not much beyond that.
