But: putting prices into the rulebook does not take up much space - and - if someone does not weant to use them and uses influence only, he still can do that.
As I wrote earlier, the instant that you put prices in the rule book, that becomes the expectation by GMs and players. The next thing you have is players getting upset because a GM is ignoring the prices of items and repeatedly saying that there aren't any plasma pistols to buy on this planet -- which players wont understand because they don't understand this background and because the book gives a price. And the players and GMs who do understand it will be pointing out how silly it is to have a unified currency in the Imperium. I also am willing to argue that money and the Influence system are inherently in conflict with each other and that conflict will lead to confusion and inconsistency.
Regarding the single currency, I'm not in any way speaking figuratively. A common currency in the setting of the Imperium is not workable. I don't mean inefficient or problematic. I mean unworkable. And a centralized one is absurd.
