By your own source, those seeking passage required stamps - approval - by the destination country willing to accept them during a time of war. In the context of the OP and my following statement, the assumption is the person would depart to another country without the benefit of the equivalent of “stamps”, approval, or wartime ethno-religious refugee status. Just somebody overstaying a tourist passport stay. So no, not really relevant. That said, I don’t disagree with getting a passport, it might be easier to ask forgiveness in another country should TSHTF in the US, but let’s not kid ourselves on it being a valid method of escape in the current situation.
