What I'm saying is, California grows much or all of the food needed to sustain ourselves, were we to become a separate country. I am not advocating this, I'm just saying it'd work better than most of the rest of the country might imagine. And we would no longer be pouring California money into the federal government to fund other states.What I'm trying to say is that, the rest of the country doesn't need Californias food. The mainland would have the south to grow crops during the winter, and the north harvests a lot during summer/fall (albeit most of the north is growing corn right now).
Not having the rest of the country to export to would probably hurt CA more than it would hurt the rest of us.
Farmers markets are already becoming a thing again in rust belt cities, though. And the local produce, in my experience, is better quality than the CA produce we find on grocery shelves.
Also, local Farmers Markets have been quite a big deal here for the past decade. All the very best stuff goes to the local markets (can't beat something that was picked on the last 24 hours), and we can grow all sorts of things year round.
