actually there are two main lines of reasoning against the coercive power of state: the moral and the practical. The moral argument says: "it is wrong to force people to give up their resources and be ordered around under threat of force". The practical argument says: "the state is a hierarchical monopolistic structure and as such provides perverse incentives for its managers and absolutely SUCKS at collecting accurate information and making intelligent decisions based on it". Personally, I don't give a shit about the moral argument, I leave that to the moralists
