most of your cattle do not come from ranches. They come from high intensity factory farms in places like stockton california and amarillo texas.
That a ranch produces any saleable livestock at all is a side-effect. most ranches are owned as vacation property.
the reason this reintroduction is opposed is the same reason you cant plant or remove any trees in Beverly Hills without a dozen lawsuits and a 3 year study to determine the effect. Stratospherically wealthy people revile change at any level and will intentionally manufacture controversy and complexity around the proposal as a defensive mechanism.
