Why should we expect that our universe will behave differently (i.e. register any difference in the laws of physics) if the origin is shifted (equivalently, if the whole universe is moved relative to the origin)? Simplistic vector algebra suggests that vector from (3,3) to (4,5) and vector from (0,0) to (1,2) are the same vector in terms of their properties—but it does not mean that having the (0,0) (and the distinction) is meaningless.
