Countries have a right to set their own immigration policy, and the assumption that people can be moved between countries with no consequence is empirically false.

Countries and peoples have a right to set an immigration policy, and this notion that we shouldn't have any borders or, or even worse than that, it's all just a blank slate, that all peoples are just the same, and we can take people from one place of the earth and we can place them in another place on the earth and everything's just gonna work out hunky-dory. Empirically not true.
