as long as I am in a democracy, open borders means more people coming in to tell me what to do
as long as I am in a socialist state open borders means more people demanding mine and other peoples money
as long as I am in a prohibition state, open borders will bring the violence that smuggling brings
for so long as these things are true open borders are like a shackle upon me as far as liberty goes and is pragmatically unsound as well, so I shall oppose it
