You can grow olives in the US and there are some farms in CA. The quantities produced are orders of magnitude off though and given the time it takes to grow olive orchards we cannot replace our imports of olives in a reasonable time period.
There's a lot of examples like this. Coffee, and bananas come to mind. You can only grow those in Hawaii, or maybe Flordia, and there's absolutely not enough land to sate our imports. The whole theory behind international trade is that some countries do things well and others don't. In the case of food the reality is more that others can't.
