I don't think that holds up to evidence. In tribes largely untouched by civilisation blood revenge is still fairly common. These are social norms, but without a neutral judge one party might execute revenge, the other party doesn't see their fault and instead retaliates, and you get an endless circle of bloodshed (which has killed entire tribes).
One of the major achievements making civilisation possible is a judge or court that can decide who is right and and who is wrong, preventing BS from spiraling in endless retaliation and counter-retatiation. In a small system that can work with just one universally respected person or person of authority, but once you scale it up to an entire country codified laws are incredibly useful for this. Codified laws means we need people making laws, which is exactly what the entire job of modern politicians is. Sure, we could have civilisation without politicians, but our countries would have to be a lot smaller than they are; a justice system without laws just doesn't scale.

Well, no? Isn't that what is called "war"? You might argue that frequency of conflicts is lower, though I would be sceptical of that without further proof.
War happens, but places without a judicial system to solve conflicts between persons, families and regions don't seem to flourish, while many of the more prosperous regions and regions with the most wealth growth feature a judicial system that spans areas normally inhabitated by multiple countries (USA, China, EU, India).
Having a transnational judicial system in the EU (as the most recently formed example) allows coorperation and trade to a much greater extend. Sure, the EU might go to war at some point, but the circle of people and corperations you can trust to respect law and written contracts is very big, no matter if a war is going on or not.
