Legit curious...why are housing wards ghost towns?

[SamSmoot]

FC houses are a thing... You can already have thousands in each ward if you have a couple large FCs there.

I've been to my FC house about 4 times since I started in January, and at most, I see one other player there. Usually none.
Because of this, I figured that it's unlikely that an FC house would bring more than a few to the neighborhood.
