After giving it some additional thought, I have an answer to my question.

Brian, I think had it as an underlying assumption, or at least didn't address it.  Basically, if we assume there is a smaller circumscribing ellipse in the original space, then because of the consistency of ratios of area (between transformations), that smaller ellipse would have a corresponding ellipse (circle) in the transformed space.  This leads to a contradiction, so the assumption is invalid.

I like it.  And Richard has a nice point about answering only the question asked, but I also appreciate the extra detail Brian gave.

Kudos to both of you.
