There is the ethical argument, there is the climate argument, and there is the economic argument. Cows in particular demand a lot of resources to produce.

Of course the IP of such a method of production could resemble a Monsanto gone wild, with meat production mainly concentrated in only a few key corporate interests as opposed to the currently more decentralized model.
