So, meat rations? Of course there will be a black market trade in them, so you are back to rationing by price again, with the slight advantage that everyone gets a "universal meat income".

I think it's impossible, and undesirable, to ration a commodity that people want, by dictat, perhaps even when there are strong negative health and social impacts, as with alcohol, tobacco, drugs, etc.

The route has to be by some form of economic penalty/redistribution, ie taxation (which people will accept to some degree), and/or through education, persuasion, cultural shift, etc.
