And that is the problem, for there exists no (functioning) society where everyone is self-sufficient. It is impossible for every person to have everything he wants for himself without depending on others. That's why we have trade, cooperation, and organization precisely because it is impossible to survive otherwise, outside of a hunter-gatherer society. Neither is it possible to have a society without government, regardless of what communists or objectivists will tell you, because in any society with surplus, there has to be management of that surplus, or else it will be wasted. The absurdity that is objectivism, taken to its natural conclusion, would devolve into little more than anarchy, with everyone for themselves, each pursuing selfish motives without any regard to cooperation.
