This Game needs a Gold Sink.
No, not an actual "Golden Sink"!
I mean a place to dump all our excess gold in large quantities because simply put we're all gathering too much of it and are running out of places to spend it, effectively making it useless.
What's the point of being rich if you have nothing to buy, right?
So my suggestion is this:
You've all seen the Gold Hoarders with their grubby hands and gold plating all around their skin due to their greed becoming manifest and turning them slowly into the Gold they covet, well why not let the same happen to us?
Allow us to give Gold Hoarder representatives large quantities of our Gold in exchange for unlocking various tiers and intensity of Gold plating throughout our body.
This would in my own self righteous opinion not only give us the Gold sink we need, but make it work perfectly within the narrative of the World and give us all access to a fantastic "Show off" cosmetic for parting with such large portions of our fortune.
Let me know what you all think. :)
