That might create odd effects. Consider. What if, right now, cows are raised using feed that's a inedible cast off of food grown for human consumption. If you tax all meat equally the incentive to do that would be reduced. You might as well raise cows on food that is fit for human consumption if it marginally improves the quality of the cow because you're paying the same tax either way.
