To which I ask: Why not place a small loop of (wire, cord, thread, whatever qualifies) on the ground in a park somewhere. Then define "outside" and "inside" the other way 'round from "normal", thus making very-nearly the entirety of the earth "inside", and the very small portion "outside".
It seems logical to me, and I've never heard a reason it can't be done other than "that's defeating the point."
Which I admit, it entirely is, but I don't see it as any more "wrong" than encircling entire cities, and it's a whole lot simpler to maintain.
