Yes, yes, Adam Smith and all. Yet, your your story represents the end consumer perspective. What I have in my mind is a long chain of linked lists that connect and break off in various areas. My point is the butcher company probably has pretty good relations with at least some of their distributors. This also might be highly dependent on geography, culture, type of business. A source of some sort would be interesting for me, because both my and your story are just that - stories, and Adam Smith lived long time ago. Robust logic doesn't need to reflect reality.
