Most of what you just said would actually reflect pretty badly on vegan diet values and improve paleo diet values.

Vegan diets are the product of intensive agriculture basically anywhere in the world. Paleo, depending on country, can be pretty low intensity, for instance, in Argentina where cattle roams free in the grassland.

While I easily concede that in places like most of the USA - where cattle is a product of intensive livestock exploitation - a paleo diet will produce a lot of CO2 compared to a vegan diet, that is actually not true in places like Argentina, or, to a lesser degree, in places like southern Europe.
