Mister Bruce is right. That is one of my biggest concerns when it comes to the dynamic economy.
If we would ignore the stability, I only have one other concern. Let's say I let my ALG boys trade our Ship Hull panels excessively with Kusari... let's create a chain: the price in Kusari falls, because they have enough. The price for raw materials on Dortmund station rises, because we produce more. That means, that we are forced to get more raw materials from let's say Elbich Mining Facility. Following this chain, the prices for food, water and oxygen on this station would rise and the raw material would become more expensive. Now my question is:
Would ALG be forced to haul these consumer goods to the mining facility, just to lower the price for the raw material? Who will do it if not we? I say, that transporting water, food and oxygen is not the task of ALG.
Please think about that. It would need way more traders too keep this entire system running.
