DS9 always seemed to reject Roddenberry's idea of 'no money', thinking it was unrealistic, naive and/or stupid. Quite a few episodes mock the pomposity of Picard's 'we work to better ourselves' speech. Notably in 'In the Cards' (DS9)
The 'no conflict' idea of Roddenberry's, between crew members, is a dumb idea too. It removes all drama.
