All true...and it imposes limits on the practicality of the approach, typically huge rectenna arrays on the ground to capture the download. I don't know what "eclipse issues" you are thinking of. Not a problem with geostationary orbit. Not a likely problem with any other orbit (lots of space up there), but non-stationary orbits mean only temporary coverage of the delivery site. No feasible energy storage. (It's hard enough to get the power, without deciding not to use it.) Inherently a space weapon due to the necessary beam control functionality, a fact that hardly anyone appreciates.
