The net force exerted by the wing, which is the integral of the pressure difference between the top and bottom surfaces, must cause the downward deflection you mention, no matter how efficient the wing is.
Yes, but as discussed before, this is balanced by upwash in front of the wing... providing NO net momentum.
Ken,

Wrong. I suspect that there is no way to get the relevant idea across. Time to stop trying.
