A steady crosswind does not cause the airplane to turn, so no rudder or aileron pressure is required against a wind.
again, we aren't talking steady state here...or else we wouldn't be talking stability. a side perturbation (or side gust) can turn a directionally stable airplane (in the direction to reduce beta), while it won't turn a neutrally stable airplane, and it will turn a directionally unstable airplane the wrong way (increase beta)
The wording of the post I responded to seemed to imply not the case of a perturbation, but a steady state, since you were discussing crab angles, with are useful over relatively long time periods, not during perturbations.
