As I just explained, it's not really about observation, it's about causation. If two objects can never possibly interact, then are they really in the same universe?
Looking out in space is also looking back in time. Anything (roughly) that is further than we can observe in the microwave background would be further back in time than the beginning of time, and therefore doesn't exist at all in our universe. It's a bit brain bending.
