We have many such outcrops of Britain throughout the World and our economy may in the future depend upon them. That isn't a problem so long as the other boys are playing nicely. Should one of them become peevish, though, and try to pinch our "lolly", we can't necessarily rely upon the UN or our allies to help us out. Unless we sign up to the EU Superstate, of course, where we all share our assets and mutually defend them.
All in all, one may as well have been born a bloody foreigner.
