We need more ways to make gold in this game.

Sorry, you just haven't made the case. In the OP, it's postulated that you can:
Make 3000gill on leves per pay
Make ~350 per dungeon run
Make 100gill per fate

You will need to spend 1k max per dungeon on repairs.
Raids are capped at 90 min, so they are the same as dungeons.

That's 4.6 dungeon or raids per day to break even. That's 7 hours of dungeons per day to break even. No deflation until you and everyone else on the server exceeds this. Assuming you are doing fates. Plus whatever other dailies they add. It really isn't an issue.

So every dungeon run, you make 350 and lose 1k
You have to do 10 fates to make that 1k repair bill...which will likely give you a 1k repair bill in the process.
3k from leves, minus the repair from doing the leves. Let's pretend that's also 1k.

so lets say you do 1 dungeon, 10 fates and 6 leves in a day. That's 3k or less in reapirs (sink) while making 5k (generated). So you break at about 2k profit without counting travel (airships, ferries, teleports), taxes (gil lost from buying/selling on market), and the other misc junk you do. Not to mention that doing a dungeon more than once puts you in the whole EVEN MORE.

So...I don't understand what you are saying....
