Certainly this pushes Occam's razor to an extreme, though, George? Aren't you
forced to admit that this "convenience" is a rather severe difference in more,
somehow, than just a matter of degree? To press the point, I can choose myself
as the reference frame, in which case I can, from the middle of my living room
force the entire universe to accelerate into a spin, and then decelerate --
complete with all the complicated math involved. To call the earth just as
eligible as anything else for a cosmologically stationary reference frame is
basically no different than you in the living room being that frame and
insisting that everyone in the world disregard the inconvenience. There is a
difference.
