You are looking at it from the micro viewpoint - one mirror/laser can not a grid make. Therefore you are correct. I look at it from the macro. Dozens, or perhaps hundreds or more mirrors, stationed all over the planet. No matter where the mirrors point their energy, or even if they are activated at all, when you look at where they are physically located on a map, you have a dispersed pattern. When they are active, it doesn't matter if they are pointing all at the same receiver, or if each points at a unique receiver, you still have a network, or grid. Therefore, I am also correct. Don't get hung up on the electrical grid that we have in use to power our homes to formulate a definition. That system is intentionally designed a bit like a fishnet for the sake of redundancy. That is not the only form a grid can take. "a framework of spaced bars that are parallel to or cross each other; a grating." I would argue that "parallel" is not a requirement either, for our purposes. Advanced Degrees in "Wrong". Yes, I have made a study of being wrong.
