a civilised world is only a category of "technological progress", they are self sufficient but are still part of the wider imperium's production cycles and will be involved in the war efforts.

A pleadure world is merely a sub category of a civilised world and judging by the fact that living on those worlds is either in service to the heroes of the imperium or given out as reward for good service, hence the war efforts are still very present.
