You're not visualizing the space geometry right. In geosynchronous orbit, you're always in daylight and you don't block anyone's sunlight.
As for the receivers, rectenna arrays do not block visible light. Farm or pasture can be beneath them. To quote the wiki article that you claim to cite:

Crops and farm animals may be raised underneath a rectenna, as the thin wires used for support and for the dipoles will only slightly reduce sunlight, so such a rectenna would not be as expensive in terms of land use as might be supposed.

So, millions do not have to starve.
Forgive me for assuming you really were as ignorant as your questions suggest. Interresting debate style you've got.
