Consider that in the US you could immigrate west and the government would give you land if you set up a homestead, at least in the mid 1800's.

There's also a literature reference to I think Little House on the Prairie where the father sees another family coming into the valley and decides they need to pack up and leave.

There is a long history of US travel out west to get land and space regardless, or maybe because, of how far away from others you can get.
