You're all out in no man's land in any case. Blue states don't produce as much food because they don't have to. As soon as they would have to, they could. They'd take a bit of a hit on the price, but that's about it. Red states don't need blue state money because they can sell their food elsewhere. (Well, maybe not to the best markets at the best prices in the current trade war climate but you get my drift.) They'd just take a bit of a hit on the price. The unhappy reality is that different regions of this nation don't really need each other for base essentials. Now, for industrial inputs or outputs? Yeah, totally different story. But that's not regionality as much as it is just "everyone is dependent on Texas and California if you go far enough down the industrial rabbit hole". Even that's just convenience though. Pretty much anywhere in the nation they can scale up to make what they need. They just don't because it's convenient to allow others to do it. As soon as those others make it inconvenient, they'll do it themselves.
