Well, you're not agreeing with me, because rings make plenty of sense. A spun station only requires only to be spinning, not a constant antigrave juice drain. Its cheaper, an lower tech, which is more reliable.
For that matter, assuming a station receives a certain amount of traffic, spin can be maintained by placing the docking ports along the equator and carefully modulating the speeds at which ships land and take off.
As for the argument of size, that really falls to a discussion of population density and growth, which is something we tend to handwave...but honestly, it doesn't deserve to be larger than the ring. (which, if any modeler wants a project, is up for grabs: the Ring is supposed to be the largest manmade object in space)
