The strength required by the tether is not the same across its length - to minimize weight, it has to be tapering off towards the Earth's end, with very light tip. So, let's find a suitable geostationary sattelite in orbit already, and bring some tape (tether) to it. 2. Space junk that's already in orbit, is great for the counterweight construction. It requires much less fuel to lift the junk into the geostationary orbit, than to lift it up from Earth surface.
