A legal system is an institution to provide dispute resolution through judicial, legislative and executive functions. The state is that which maintains in large part a monopoly over force, geography and the legal system.
What’s wrong with a forcible monopoly? You are saying that you are the only one who has this right. Under anarchy there is equality of authority. No one has monopolies of force or jurisdiction. Dispute resolutions are referred to arbitration. Anarchy is founded when one bypasses the state into voluntary system and the state withers away. The bypassing strategy [voluntaryists] seems superior, but has little history of success. The takeover strategy [agorists] seems inherently unjust because it is using the same power, like voting.
