<p>@PengsPhils @Ctesiphon I wasn’t referring to communism or any sort of argument against it (I’m well aware of the human nature argument) when I said something along the lines of “let’s not kill everyone.” I was merely referring to the actual problem - the internal (and changeable) human condition, not how we organize society. </p>
<p>Also, if you want to get technical once again, the concept of the free market and voluntarism is in our lives everyday, constantly, on a micro scale, which overlap with what I think you call communism on a micro scale, and cooperation. </p>
