Actually provide an argument instead of just asserting this.
On earth, deployment of a built solar panel is screwing it into a dirt cheap frame on the ground.
To deploy a solar panel in space, you must attach it to a satellite that no one involved has even pretended to claim is designed, so you need a factory for those on the same order of magnitude as your panels, you need enough boost capacity, so a factory for rockets, and a much larger fuel industry, and then you need all the immense engineering required to do any of that at all, and then you need to spin up the industries to supply this brand new industry, and then you need to manage all those satellites in space, and then you still don't get any actual power because it's all in space so you haven't scaled SHIT
It's all absolute horseshit. No, none of this is planned. He's just going to cash in on the IPO.
