I agree that modern transport and communication has significantly changed peoples abilities to migrate. Wouldn't this mean that eventually the world will be more integrated in every dimension, regardless of the desires of those controlling borders, that lower barriers to communication and transportation will continue to make the world a smaller place? Will it be possible to stop this as the decades and centuries go by? There's already millions of people crossing borders every year, like the southern U.S. border, refugees from Africa and the Middle East into Europe, migrants leaving Russia and Ukraine, migrants between countries in Africa, Asia, and South America, etc. One might expect those numbers to increase over time, as it gets easier to travel. Perhaps it is inevitable that the world will continue to integrate.
