Inland farmers require foreign oil as an input to the caloric production you describe, which means that to survive they need the ports and pipelines of North America as well as the cooperation of oil-rich nations.

This is why I said all the current informal federal-based stuff would come back through treaty. I think most people on both "sides" are reasonable, so the split would never actually happen. And if it did, people would quickly miss all the stuff from the other side of it.
It's on a level with considering what happens if the sun disappears. It can't happen without something freakish happening, and none of us really knows how it would go.
One side would devolve into an unlivable hellscape. The other side would devolve into the 1890s-1910s or so, without access to modern imported goods.
Nobody would "win". It's obviously a horrible scenario. But one side would definitely lose.

Nations collapse from political schism all the time. We just have short memories.
I do not believe the people yelling "secession!" are prepared to revert to a pre-WWI world.
And if your supply requirements decrease by 150MM people, that makes the job substantially easier to manage.

Ah, but they think they are. Which is really the only thing that matters, since beyond a certain point, it's too late.
Subsistence farming is great for feeding an army so you can rebel against your government
I first read that as downvote, you know the internetizen apocalypse
California produces almost 14% of all the crops grown in the US. A large portion of that are nuts and high calorie items like avocado and soy. You want food oils? Grains? Meats? CA exports all of those. CA is the 4th biggest producer of cattle in the US, 10th biggest poultry producer. 9th biggest producer of potatoes (Washington is #1, another coastal state). 2nd biggest rice producer.
As far as energy, you realize Texas is also not one of your flyover states, right? And even if it wasn't, we import plenty of energy from pipelines to coastal states so it can be sold or refined. CA has nearly the same refinement capabilities as Texas itself.
Fly over states are land. Undeveloped land is not extrinsically valuable.
Even so, produce does not comprise a material percentage of the US caloric intake. Grains, tubers, grain oils, and meat definitely do.
Beyond food, there's mining and energy. Without the coasts, The US would be significantly inconvenienced. Without flyover country, the US would be dead.
