Your economy will die like any other because money will fail to circulate. So you will come up with nonsensical concepts like money sinks and faucets. Imagine an MMORPG where the money supply was fixed and 90% of the playerbase quit and took 90% of the money supply with them. That money will not circulate. It is dead money. Dead money means a dead economy.

As stupid as it sounds, every game economy has adopted a Keynesian/pseudo MMT (faucet and sink) model because that is way more fun. The Austrian economists on the other hand know how to make unfun games. Translate that to reality however you wish.
