The parodox of life, which I spent so much time thinking about, was that big things are easier to change than small things. You could destroy a monument with a couple of stacks of explosives, trivial to produce. An entire empire can fall with the right rumor, enough FUD. Sure, there were the unbreakable arches, built before the patches, made of the same stuff as the basement of the world, but those were few. An oddity, at best.
