Ancaps believe in the free market. We have the right to trade and exchange property with whomever we want to. Those that practice aggression against others, and violate the property rights of others are really the only people that would be doing a negative. People simply would not do business with them

Anarchism is based on free association. You are talking about it here, when you say people can choose who they want to do business with... But you don't seem to allow for the same sort of thing to happen in an anarcho-communist society. You keep talking about people being greedy and lazy as if nobody had any choice whether to associate with them.
