Happy you found it helpful! The final section (imposters) of this [1] simplified exploration of “green beard altruism” might be of interest to you if you want to explore this further. If you’re interested in thinking about things like this generally, these are Nash equilibrium problems and the field is called game theory. In answer: if we do discard the assumptions of game theory and we imagine nobody would ever think to “cheat,” it could work. But in reality it wouldn’t be just that some countries have huge advantages in some industries— they would have huge advantages in every industry. People and companies looking to maximize their opportunities would flee to the country with the lowest effective (nominal doesn’t matter) tax rate which could also guarantee their safety. This is actually part of how the US ended up burying the Soviet Union/eastern Bloc with economic productivity— we kept poaching all their best engineers, scientists, mathematicians, and entrepreneurs.
