To be fair, the economy on the cloud server is... well, literally everyone has been told "the world is ending next Tuesday and you don't get to keep the money" so nobody is spending it in a rational manner. There is no need to save it for the future, and very little need to earn more than you started with.
If someone is charging a million gil for something that would normally cost 100 gil, whatever. I get on with my game and they get to roll around in their virtual money pit for the next few days, and we all end up back where we were. It's hardly any different than if they were selling it for free.
