Negative Dominion causes unrest. Battles cause unrest. Blood Hunting causing unrest. These are all "natural" reasons for unrest in your provinces. Left alone with positive dominion and no battles and no blood hunting, outside of Spies, Globals, and spell factors the unrest will not rise.

You forgot hidden sites and random events, some of which have sorta vague descriptions. No need to automatically assume espionage whenever one of your provinces' unrest rises above zero.
