Also funnily enough items being in the gacha roll makes them cheaper overall. Since people are forced to get duplicates of things they don't want they'll chuck it on the marketboard and undercut like mad. It takes time to build up 6000+ points for the shop. You can buy a 6000 point item, sell it, and buy anything you could want from the gacha. If the mount was 9900 points, you'd actually be worse off. Not to even mention the dyes, which are absolutely dirt cheap.

Will this be the case in the future? Who knows. Coffer o' Kupos and casual wear coffers are still sitting around 100,000 gil a piece though if Ishgard restoration is any measure.
