I don't think war is necessary (and looking at things like the "war on terror" that spawned a lot of rules, it might even do the opposite).
Societies can do "de-sprawling" of rules, but it isn't a frequent thing (the German civil code is kind of a reduction of lots of several codes into one, for example).
There is probably also an element of aging societies becoming more risk averse, hence more rules and regulations.
