This is the whole debate between the (global) "free market" and "autarky." If you are properly indoctrinated in the principles of capitalism and a free market, it is very seductive to think that what is proper to prevail in one's own nation, should also prevail among other nations. What is forgotten is that a free market is utterly dependent on an environment of liberty and the protection of personal and property rights. No such environment internationally. Thus the argument for autarky, or being sure you have enough agriculture, industry, and business to sustain yourself if cut off from the world market...through world events... Not a lot of people understand this.
