Why the Chuchik Can't Punish the Guilty Party

A bad scapegoat would be like Agamemnon sacrificing his daughter, right? Gerard's surprising conclusion is that for a lot to work the way it does now and so effectively, where the guilty party is punished, there must be a totalizing force handing out the punishments. We can punish the guilty party because we are not like the Chuchik with separate roaming tribes. We are one big tribe with an entity that has a monopoly over violence, which is the state. If someone harms you and you don't like the sentence they were eventually given and try to take justice into your own hands then you will be threatened with the state's vengeance and violence in turn.
