If the numbers were anything CLOSE to what you are citing here, you'd have a point. They're not, and you know it. I've lived in this world for 15 years and built real, no-nonsense commercial networks the entire time. Reality isn't a dream, or a wish, its reality... I also have no financial stake in this debate or my position in it. That is, no firm which I own, operate, work for or own stock in wins or loses if you (or I) am right.
