While I agree that busses incentivise over-production, my only argument in their favour stems from SWE design best-practices of maximising cohesion and minimising coupling. The benefits of a bus is that it makes it easier to create factory districts that can be scaled independently of everything else. I suppose the question is how independent/integrated should these districts be? Should they only create ore? Or create utility-science-packs?
