A passive community based market might be nice, but there still wouldn't be much motivation to trade for gold instead of items-for-items without useful services/items that could be bought with gold.
If I'm guessing correctly (dead frontier), the game you're referencing has services like adding dye to armors, or upgrades to weapons/armors at the cost of cash.
Examples:
The blacksmith in sorcburg (assuming he charges a lot), might have such services.
Titles that require the sacrifice of certain items will probably do a lot to motivate players to trade anyway, since players will probably want to switch titles pretty often.
Temporary weapons (powerful ones) as mentioned earlier would also help a bit, as would items with limited charges via staves that cast powerful spells/flesheater's curse/titan's arms/etc.
Generic mmorpgs usually have an upgrading service, where you pay increasing amounts of gold to upgrade items, with a chance to fail/remove upgrades/destroy the item. Not sure if this is doable with MSC though.
