With a space elevator, don't you need a mass some distance above geosync to hold the weight of the cable and the payload as it ascends?

I think the counterbalance is more to make sure that the center of gravity is actually the thing in geostationary orbit.

Yeah, it's not the type of thing you can iterate on and get usable results for without the whole thing. It's not like you can build a tiny space elevator and use it to bomb London, for example.
