Less money = your money is worth more.

I'd rather the economy not get out of hand so people can charge out the ying-yang for stuff like in other mmos. It pushes the new player base way out of the game because they just bought it and they would have to spend 2 years farming for 1 item. I like the fact that your gil amount will be low as my gil will be worth more. If you don't want your money to get a market cut, then dont put it on the market.

thats all it means. people will make money if they really love it that much, not that there is very much use for it anyway.
