The author has a very interesting point. Still he oversimplifies and so I didn't find the article very insightful.
For example lawyers are there for good reason. Modern society needs a way to officially settle conflicts. But our law system creates arms races and draws more and more resources this way.

So the interesting question would be how to avoid arms races. But that is not even mentioned.
