Now imagine you're hiking in the woods and, all of a sudden, you reach a fence with a sign "PRIVATE PROPERTY NO TRESPASSING". Years go by and even more rich people build such homes in the woods. Now you're hiking in the woods, constantly passing through gravel roads leading to these properties and hearing traffic noise of a more major road where some cars from some of these houses went to fill the propane tank, buy food supplies or whatever.
