Targeting ads at an aggregate demographic (like you would with a billboard) is not the same as targeting ads at a specific person because they match a desired demographic. It would be more like some guy with a sign recognizing you and running up to you to wave the sign in your face specifically.

Also: I would argue that there is support for "Outside", as you put it. Fire dept/ambulance/police for emergencies, government at various levels for some things, utility companies (e.g. if a water line broke or whatever), etc, etc.
