How long would that rope need to be in order to not just fall back down to earth? I.E. the crossing point between gravity and centripetal force

    Depends where it is anchored. If at equator, geostationary orbit is at 35,786km so zeroth-order approximation is twice that. If at a pole, it will always fall back to earth for lengths less than current lunar orbit (because there will be zero angular momentum).
