The current items that are expensive are going to be some of the best in the game. There will always be really cheap items to help new players get started. It is still a zero-sum game, so those who get the cheap or "free" items will have less potential reward, but could still get lucky and loot better gear that helps them advance to harder dungeons. There are also plans to stop high-end players from farming the easy dungeons (or at least not make it worth their while).
