Trading was and is the base for every clan. The goods an the money were provided by the traders to build warships for pvp-purposes. At this very moment trading in goods for shipbuilding has become impossible. Neither trading in goods gives you any money.
The old trading system was ok. It needed improvement as the whole game needed to be better balanced. E.g. the game has to be again nation based and not clan based. Historical corrections to the game like deleting the endinorog guns from 1780; and so on and so forth. Russians in the Caribbic????
