I don't think you're discussing the same threat model as the author. You're talking about fighting an army. He's talking about other dangerous, non-military people (e.g. Another gang of survivors, who happen to have guns while you just have food)

To be fair, military presence is certainly a problematic situation, but it seems more likely you'd encounter other, uh, less-than-savory people out there in an apocalyptic scenario, who are more likely to be dangerous to you than military personnel.
