Most crops grown in the US are used as animal feed. They are dependent on arable land that could be used to grow food for humans directly and much more efficiently. We just like the taste, so we accept the inefficiency.

Eh. The "inefficent calorie conversion" take is sort of lazy and misses the nuances. I just looked it uo, and it seems that only about 55% of yields are for feed, and there is definitely some more nuance there, since a lot of feed meal comes from stalks and parts if the plants humans would not consume. This notion of calorie inefficiency also misses the mark on what would be planted and harvested instead to contain the same bioavailable nutrient profile thay comes from meat. In otber words, using land for feed to convert grains to another type of food is probably more necessary than just "taste".
I don't care to research it further, but I own a small 5 acre farm and can attest that some crops grow in some areas and some don't. So even if you did map it all out on a piece of paper where you'd get all your beans and lentils and whatnots I doubt it would work in real life. Cattle can handle a couple hard freezes. My tomatoes can't.
