You seem to throw all food processing into the same pot, so to speak. Humans have an under-developed digestion system. Why? Because they can pre-process their foods to compensate. They know that some plants are poisonous unless cooked, for example.
And obviously, few food-processing factories or bulk shipping methods of ingredients cause enough greenhouse gasses that you can just eat local meat instead, if you care about your footprint. Saying that none of this is solving a real problem is wishful thinking.
