Global freedom of movement was an inalienable right until European colonial powers noticed some of their colonies' peoples wanted to move to Europe.

Large scale global movement is indicative of failure to uplift the globe from violence, poverty, and climate change. It makes a lot more sense to me for the global powers who don't want mass migration to do something to fix its causes instead of retreating inward and succumbing to nativism.

What an absurd assertion. Where did you learn that? Read up about Roman border control and immigration policy, and what they required of immigrants into Roman territory.

There was no global freedom of movement. Ever.
