That it in turn would imply that a person living in such a town can walk no more that 2000 amos in any direction on Shabbos, which seems small to me (the shul I attend is 1.1 miles from my house, and 2000 amos is around 0.6 miles; luckily I live in a much more densely populated town).

Lich'ora, if the property is fenced (and thus a reshut hayachid) one
counts the 70 2/3 amot from the fence, not from the house.
