Greediness: Far less likely in a post scarcity society,
I'm not sure I believe we'll reach that. Perhaps I'm too cynical about this, but there'll still be posessions doubling as status symbols. Most probably will be stuff that by definition very few can have, e.g. spacious accomodations at the Champs elysées in Paris, or smack in the center of whatever metropolis you fancy. Original works of famous artists. Hence, even in a replicator economy, there'll probably still be 'scarce' goods in that sense, and therefore, greed.
