Where did that come from?

I said they could produce everything they need to live and eat, while trading oil for whatever they couldnt produce themselves.
Like microchips, or outside help building their own factories so they can.

I certainly wouldnt advocate only producing oil.
Nor banning people from production they want to engage in.

As for communism forcing things on people, i thought we were past that, communism, as defined by anarchists, doesnt include force.
