Logistics is hard. On top of that, importing food is a very political subject. Do you want to feed everyone in the world as resource-efficiently as possible, or do you want every country/region/city/neighborhood/community to be equipped to feed itself? Bear in mind that these two are very much different scenarios. Small, poor, inefficient farmers have been bankrupted by cheap imports they cannot compete with more than once in world history. Similarly, price controls on food have led to famine more than once. This is without even touching on the point that a lot of poorer countries really want to be able to export food for a profit. I get the sense that the short answer to your uncomfortable question is simple: yes. With the asterisk being all the political and economic questions that go in it and don't have simple answers.
