It seems you don't get it. Dynamic economy means, every time the server restarts (update), new prices and items are sold everywhere. That doesn't stick with Red Crystals (you will find out later), Pods (Only on Prisons) and Cargopods. That "logic" you mentioned doesn't have anything to do with Dynamic Economy. The base buys as much as it wants. The base sells as much as you can haul. That's all.
