I don't see how this has been brought up so many times and noone really mentioned the most important part.....

SE want the economy to drain a bit. Thats why they removed a decimal from 1.0 currency base. They want to even out the gil as much as they can (obv hoarders will be an anomaly) and then I assume they will bring in gil with a patch (increasing quests, dungeon drops, dailies, increase guildleves or a combination) which will easily allow them a soft reset on the economy without a total crash or wipe.
