When human beings live in proximity with each other, they will end up in disputes. A modern, highly ordered society requires a lot of people to live in close proximity to each other, because there are many processes that require productive individuals to live near where productive processes take place. Disputes between these people are an inescapable result, and there are essentially two options. You can either force them to argue for their viewpoint in a structured way, have someone rule on it, and apply that ruling to similar disputes later. OR you can just have a shithole country where every dispute is a niggerfest where people attack each other and then their family members go on a revenge raid etc.
