Ah see, this is the problem though.

I agree with all you’ve said.

But… CSA won’t feed 8 billion people.

Full stop, it won’t.

Not without a magically generated total overthrow and reworking of world capitalism as it exists, toward some kind of eco based localized socialsm or something… yep, it would be nice if that would happen, but magical thinking is dumb.

So, that can’t be the generalized proposed framework for the future, unless you’re just fine with a few billion people starving to death.

Bugs though?

Might be a more cost effective solution for protein that can actually work at scale, allow CSA to focus on the healthier and more sustsinable plants, and bugs as a protein source would probably be a hell of a lot less resource intensive and more sustainable than… our current level of cows, chickens, pigs, etc.

We use so much farmland to grow food for pigs cows chickens.

We could probably use a lot less farmland if that went to feeding crickets or something, and then use the saved farmland for healthier vegetables.

At least, this is my rough and broad understanding/idea.
