That was not how I read the article at all. What it is arguing is essentially that people benefit from the presence of order, especially when it includes larger numbers of people, but that historically such order only tends to come about through warfare. By all means disagree with this—though you might consider reading the article if you haven’t so that you are responding to its actual points—but it has nothing to do with people doing better merely because they have survived the war.
