  It’s hard to come up with a succinct reply to highlight how utterly absurd this argument is. From virtually any physics-based perspective, any kind of space travel or space-faring economy outside of very, very near Earth is unavoidably an net-negative venture[1]. Shipping energy from anywhere outside of Earth’s gravity well costs more energy, even at theoretical optimum efficiency, than it has any chance of gaining. It’s not just that it’s difficult, from any meaningful angle it requires us to have completely misunderstood the relevant physics. If your argument relies on us discovering that all of known physics isn’t just off a bit or needing of refinement, but is completely misguided… well, that’s your prerogative I suppose. Even if you hypothesize a space-colonizing human race, that does nothing for the people who are still stuck on Earth with Earth’s finite resources.
