- It can be abused.
- It will clutter the castle yards.
- The same structures can be built outside of the castle.
- It will make a castle more subjected to break-ins using bugs or otherwise.
- Ranks and rights are under the jurisdiction of leaders most of the time, and not all leaders make wise decisions.

No, I don't think people should get special benefit to live inside the castle walls. It defeats the purpose of having a stronghold. You might as well just build big walls around the entire island.
