There is no such thing as the freedom to travel. All travelers can be denied entrance at the whim of that country. Banning travelers from Liberia and Sierra will prevent a few other cases getting in, and cost us a pittance in lost trade.
See? Scared enough to force others to suffer opportunity costs, but not scared enough to make token donations.
Agree to disagree whether travel is a freedom. I mean, it is, we just don't pretend it's a right.
