Complete chaos is rarely suitable for anyone trying to gain power either, you realize. If the entire realm falls apart, what will they gain power of? Besides, one needs supporters to plot properly.
Most commonly, it won't be people trying to cause chaos, it'll be that everyone is plotting for themselves. That's what causes chaos—and, more generally, when people don't care about working together as a realm/team.
And you'd be surprised—you'd be disgusted—at how many people think they can run a serious plot either all by themselves or with one or two supporters (their OOC friends, usually). The problem being, of course, that you otherwise have to resort to actually
trusting people.
