Ridiculous. Completely hypothetical argument devoid of any real-world considerations.

Reducto ad absurdem -- A single crack-house can bring down the value of every house in the neighborhood by 100k or more.

Housing has huge externalities (traffic, parking, noise, crime, property values) and a lot of what makes a property a "good" property is having an area where those externalities are controlled so you can walk your dog safely at night.
