Those are the most solid arguments I have ever heard on why the state being in sole control of national security is the apex optimum of an ill fated strategy. It's all of what you just said but scaled to the absolute maximum possible plus having sole right to it by law. It's an extreme application of all the weaknesses you listed to such an extent it sounds surreal. It should be violently evident and stab people's logic right in the eye how bad of an idea that is, precisely due to all of what you just said, couldn't agree more.
