i dont think it has anything to do with transport or franchising. some areas of post roman britain do not have pottery and dont start using it again for several centuries. in the southwest they import fancy pots by sea, on the east coast they make it and transport it within their region. most everybody else clearly dont think it is necessary and can do without it for hundreds of years. these same people for the most part trade in metal and jewelry but they dont build houses we can recognise. they are living differently and they had different prioritise.
If they can get you asking the wrong questions, they don't have to worry about answers
