The gil issue is because of lack of crafting and gathering. Stuff is just to easy to get. I hate to say it but its true. When you make it so its very easy to obtain the supplies and make it HQ almost every time, people don't see the profit in it and treat it as a NQ. Again hate to say it but crafting HQ items is to easy. On top of that, people keep reducing the price on many things that were worth farming and now they are not because because its just easier and almost cheaper to just buy them because you get almost 10k gil on one dungeon run and repairs cost 2.5k-3k gil on iLv80+ gear when they are running low after 4-5 runs. As of now, people that craft can't make gear w/o binding materia to it close to get close to iLv80+ gear. If they do try to sell it, people just use the stones to buy their armor because they don't want to or don't have enough gil to buy the set and stones are easier to get than gil.
