The colonial core presently has an abundance of dairy because its depriving the rest of the world of resources and digging its own grave with cattle. So its not so much post scarcity as it is that the major fraction of all cows milk that will ever be produced on Earth is being produced all at once and in a few small areas, and you're paying for it in human blood (also many other creatures' blood).
Sorry, post scarcity is just a real specific term for not what you have.
