Compare when Picard said people have moved beyond the need for personal possessions to Kirk's collection of antiques in his apartment.
I thought the line was "the acquisition of wealth is no longer a driving force in our lives..."
Or something to that effect.
I mean, everyone on the ship had possessions. Picard had his tapestry, flute, and photo album. Even in the Roddenberry era of TNG Picard liked his "stuff", going back to Stargazer to get it.
