Wouldn't you use both anticlockwise and clockwise runways if you had a circular airport? You could then have 2 active runways that were into the wind. So long as they were long enough, you would have room to abort a take-off before you came into conflict with the opposing runway.
My general feeling is that when clever people suggest something that seems to be stupid, it's generally worth giving some unbiased consideration. My problem with the proposal so far is that I haven't seen enough detail about it so far to have any inkling as to how it's actually proposed it should work.
