It would cost a lot more, that’s just the cost of lift raw tonnage of the carriers themselves. You also have to lift the machinery to assemble and maintain them, spares of pretty much everything, and the cost of developing and lifting all of that. I think we’d all be looking at the “modest” billions inflate into enormous trillions before we knew it. Of course if it actually worked it would potentially be worth it.
