The fact that a powerful microwave beam shooting precisely from the orbit is also a weapon platform (if directed outside the receiver) might have played some role.
With modern modular designs using phased array transmitters, even getting that much focus requires a reference signal from the ground target.
Really though I don't see this scaling to energy production for the masses due to the beaming logistics.
It'll mainly be used to recharge drones that never land and possibly fry enemy systems / missiles / etc.
