I don't recall exactly but there is geostationary and there geocentric orbits.
The orbit that is not zero inclination will trace a figure 8 in the sky but its not a large deviation in position. If 5GHz is being considered for the link, antenna gain may be fairly high but will they have a beamwidth narrower than the angular deviation that the figure 8 makes? How big a dish? 2-foot? 3-foot? Get out your sliderules and calculate the beamwidth (no I will not do it for you).
I think the inclination in geotationary is not very high (maybe a few degrees; i.e. <10). The apparent motion would be diurnal so nothing rapid. One could probably use a manual setting for a few hours.
Just a guesstimate.

While it appears that you are right about the link budget, one of you arguments holds only *some* water, and that is tracking. GeoSTATIONARY birds would require to tracking, but there are geosynchronous orbits (i.e. 24 hours, but not necessarily 0 inclination and 0 eccentricity) which would move north/south or east/west in the sky over the course of a day.
And regarding the moon: Another argument against it is that it is darned hard to land on the moon. Lots more deltaV required.
