In no way, shape, or form does any sane person need 1400 inventory slots of bank space. Having one extra glamour set for EVERY class (Weapon, Head, Chest, Legs, Feet, and Off-hand) results in the use of 147 inventory slots. Unless you enjoy keeping multiple dye versions of the exact same piece of gear, there is absolutely no way that you would ever need that much space, and neither does it give you any advantage over another player just because you happen to have every boot model in the game for your White Mage on hand at any time.
The problem with this logic is that anyone can make 9 character alts in their own little free company and get 18 more retainers, totaling up to 360 more items for sale at once without paying a single dime. If it hasn't already broken the market board then it won't when people can do it on a single character. If anything, you're paying for the "convenience" of not having to log in & out to check your stalls.
You do realize you have to gear, level, and manage all of those retainers, right? Not only is this a massive undertaking in it's own right, but retainers NEVER return with relevant gear or items, and once again only benefits players who are trying desperately to get rare glamour gear like the unobtainables you mentioned. Considering that you're still severely limited by your Venture income, this doesn't make it pay to win in the slightest. Just because you "play different" doesn't mean you can go crying out on the forums and accuse a perfectly fine cash shop model of being pay to win. If you want a good example of "pay to win" look at Air Mech Arena on the PS4 where it's a competitive game that has it's best items behind a pay wall.
You do realize that in order to implement such a system that they'd have to completely reprogram the way that the game works, right? Not to mention the dire effects it could have on the economy since they haven't been keeping track of the gear you're putting on up until now, so you'd see a spike in old content items that have no business being so pricey.
