This exact same technology naturally allows capitalists to force everyone to pay not to have their sunlight blocked during the day.
I mean, the technology certainly has benefits, not in reflecting sunlight onto the dark side of the Earth. Nobody fucking needs that. Instead it should be used to shade a few percent of sunlight in order to control Earth's warming climate.
But rich people gotta fuck things up. No single entity must ever be allowed to control orbital megastructures.
