The state has far too often been an instrument for facilitating wars and other acts of violence.  The state has, throughout history, been responsible for an immeasurable amount of violence and destruction. From ancient times where states were the primary instrument of enforcing laws so that people could keep slaves, to the actions of imperial nations like Britain, to the holocaust to all of the pointless wars fought throughout history, states have a long record of slaughtering and ruining the lives of countless numbers of their own and other states people. William Eckhardt estimates battle deaths since 3000 BC at 151million while Beer came out with a much higher figure of 1.1 billion battle deaths (NB both use dodgy calculations and of course in either case the total military deaths let alone civilian would be much higher).1  These actions are always taken because they are in the interest of the ruling class, but the ruling classes are never the ones directly involved in these conflicts, they instead use the state as an instrument to coerce other people to fight their battles for them. In a stateless society the people might need to fight against oppression but they would never be forced to fight for causes that have nothing to do with them.  [1]
