Even if you could convert all the corn/soybean land in the United States to more regenerative methods, you probably wouldn't be able to meet the current demand for meat. Additionally you have a logistical problem with the animals being distributed across an enormous area vs concentrated in a CAFO. Now, you would easily be able to grow enough food for the country and possibly the globe, but meat demand cannot be sustained.
