Perhaps but war was posited of a method of "clearing the books" and allowing significant reform. If that were true you'd expect such societies to be less weighed down by bureaucracy than others that had no such opportunity.
Germany and Japan have had reputations as being somewhat bureaucractic for decades though, which says to me war had no lasting impact, if any at all. I.e. a very expensive way to achieve nothing.
However if the present legislative burden is excessively oppressive, a war, revolution, or reconstitution might address same.
Your argument is a non sequitur.
