"Doing something about it."

People don't even want something to be done about it.

They only have two options:
a) Triple to quadruple the total wards, spreading them according to realm pop
b) Disown and reimburse all personal house owners, make wards FC only, minimum 3-5 members with auto demolish if you fall below that, then work on instanced personal housing.

Those are the two ways to effectively tackle the issue. First isn't gonna happen because it would cost them money, second isn't gonna happen because personal house owners would cause an uproar.
