I said beans and other plant proteins which includes soy, hemp, legumes, oats, nuts, amaranth, etc. which are already grown in the US regions where land is used to graze cattle. Not sure why you're singling out beans.

I'm not singling out beans, just using them as one example. All of the other plant proteins you listed have similar quality issues.

Soy is a complete protein. IF you need all the essential amino acids, you eat a variety of sources. https://www.chhs.colostate.edu/krnc/monthly-blog/plant-based...

>It's certainly possible to get near optimal ratios and quantities with a mix of plants but this takes a bit of planning

This is true for any processed food. And I’m using “processed” liberally here. Meat must generally be butchered and cooked before consuming, but we’re just so used to it we don’t consider it “processing” or “planning” to do it.

So much planning! You have to eat beans AND rice to get all of your essential amino acids. That's two whole foods! Ah well, too complicated. Instead I'll grow alfalfa in the desert to raise and slaughter cattle. I'll eat just the meat by itself, and now I've got zero fiber but I don't have to think about all those complex amino acids with my feeble, plant-based mind.
