As an avid market player and crafter I understand having over 1 million gil and what to do with it... go to the casino, blow it on a slot or blackjack or mai jong instead of needing mgp because as of now I make 1 million gil a week so in total after 5 months I had 80,000,000 and not interested in buying a house when my fc has one with all the things I need. So, my thought, blow it on card games n such, why not, the ratio to win at a casino is like the same methodology in a game as you will never win except on a 15/85 scale.
