That may be true, although it doesn't really address the parent commentor's line of argument: in environments where few (if any) people are allowed to have guns, concealed carry isn't necessary, and gun crime is rare.
His argument was that a lot of people being armed leads to regular standoffs. CCW being very common and leading to almost no standoffs over stupid arguments absolutely does address it. I'm ignoring comparing individuals to nation states, which is just silly.
