If we were to implement something like this, it would have to be a constant drain on the region's stats.
People who are told they can't leave will not be happy about it, whether or not they wanted to leave in the first place.
Well, how many peasants leave per day? 10%? To me, that sounds like a 10% penalty to morale.
I'd like to have some sort of control over how many peasants per day can leave, so that I can cap it at 50 peasants per day, or 1% of population, or something.
