I sorta doubt this is the guy’s point, but I think you can think of such a force. You can think of this hypothetical force as an entropic kind of force, there are many plausible ways for a civilization to break down than for it to continue or grow; being a civilization just makes you vulnerable to many kinds of problems. In order to maintain a civilization, you need a different force for larger civilization to counteract this hypothetical force.
