It doesn't break. It's being broken on purpose — you cannot own a town.
Towns that used to have an invested owner are often famous for their excellent design. See Zamość for example.
It was built around a textiles mill and was designed and planned according to the wishes of the mill owner, one Titus Salt. One of his stipulations was that alcohol was to be unavailable in Saltaire. The first bar only opened quite recently - called Titus's. :)
