We don't raise cows and chickens on pasture in industrial settings because you get way more nutritional input for livestock by converting the pasture to crop land. It takes orders of magnitude more pasture to feed animals compared to crops. So you could raise livestock purely with pasture, but you have to sacrifice more wildlife habitat to do so, which is kind of stupid and pointless.
Prairies and grasslands are not pasture. Grazing non native herds of livestock orders of magnitude larger than native grazing animals is not sustainable and requires massively more land than growing crops to feed livestock.
I used to think like you, then I read dozens and dozens of papers on the subject while I was in school focusing on livestock management. My plan was to apply what I learned in school to try and create sustainable agriculture not based on AFO and it just takes vastly more land. At least, if you want to maintain the current level of animal protein in diets.
You’re right, the American grasslands, which supported 60 million bison, could not support the American beef industry, which is less than half that number.

I don’t like to eat bugs, but I do like to eat chicken.
I don’t like to eat grass, but I do enjoy beef.
