As I look at how much work it's going to be to incorporate a brick wall into our existing town - and hear rumors about even more stronger walls - I wonder if part of the pvp arson patch can be a mechanism for easy self destruction of portions of our base.
The following ideas aren't great - but will get the conversation started:
1) A dynamite item from the NPCs? I guess raiders could use it too - but if expensive enough they shouldn't have an incentive to use it much
2) Mayor only right click destroy permissions
3) Destroy takes less phlegm when you have permissions on the claim
