The issue here really is not whether international trade shall be free but whether or not it makes any sense for a country - or, for that matter, a region - to destroy its own capacity to produce its own food. How can a government, entrusted with the safety and health of its people, conscientiously barter away in the name of an economic idea that people's ability to feed itself? And if people lose their ability to feed themselves, how can they be said to be free?
