Economically a great idea, but I would probably stop paying attention after a while, and then find that someone had snuck an army in my province via a sneaky sea route. At least with 100 peasants in the castle, they have to siege the place before they can take the province, by which time I would have a real army there.
Nope, the less than 100 men comment (bandit rebellion) is a type of rebellion, not something that occurs even when the loalty is high.
My usual garrison is the govenor, and if he got stars it's possible that the province is completly ungarrisoned. I try to avoid though as you said, emty provinces fall immidiatly, although the common reason is rebellions due to disrupted shiplines, not the enemy.
I love one man garrisons though
