Another compounding factor involves legality of selling meat.

You can sell live animals (and fractions of them, e.g. 1/2 or 1/4), which are in turned butchered for the customer, but you can only sell cuts if they are slaughtered at a USDA-inspected facility, which is relatively rare. Since most folks don't want to buy that much beef at once, it severely curtails the audience.
