Those aren't roadblocks. Those are targets. Unless you've built forts or strong garrisons.

Even demonic/undead garrisons have opportunity costs. They aren't counterattacking/raiding your enemy. The mage is summoning not bloodhunting, etc etc.

And the other monkey nations have cheap priests for blessing and upkeep-free sacred summons right? If you really wanted to stop raiders, a couple of those in each province will stop your "200 gp force" dead.
