You can’t really export food if you live there. Food in general doesn’t even travel that far since it has all these special requirements. Yeah yeah you have some fruit from halfway across the world, good for you. The milk, eggs, and bread you are eating is a different story. Farmers need a good transportation network and a market that needs what they grow. Drugs are much more shelf stable and the price per unit is much higher.

Well you can still grow food for yourself which is great except it doesn’t give you cold hard currency. Currency you might need if say you plan to be able to deal with a bad growing system.
