It, really really depends
You can have some hidden markets, you can get some ultra rare drops, do external services like say, gpose requests or run a thing/work on venues(These generate A LOT if well made) roleplaying and SPECIALLY ERP
Along just comes the enough time to amass
But I agree once reached a certain point gil becomes pretty much useless, I'm sitting at 250M and even I know I won't use more than say, 50 mil on the next 2 years unless I play dumb or go crazy buying mounts I'm too lazy to get(AKA criterion)
