Unless your neighbors are convicts or something, they have access to the legislative process. If you're doing something on your property that annoys enough of your neighbors, those neighbors call in to a local representative, an ordinance gets passed, police show up if you keep doing it. This can and does happen. Maybe you live in a county that's really lax, but still there are local laws in place that got there pretty much exactly by some neighbors getting together and bugging their representative.
