How do we know that elite families in the gulf countries haven't just created tons of money out of thin air?

The finances of the elites in the oil rich gulf countries and saudi arabia have always been as opaque as they can be. It is assumed that the wealth they have on their bank accounts might be numbered in the many trillions of dollars, and that this money comes from oil revenue.

But, given that there is no separation of powers in those countries and in no way the central banks are independent, i can't seem to argue against the position that they could, if they wish to, just print unlimited money (in their national currency) into their excel balance sheets like if it was some kind of age of empires cheat code.

Normally this doesn't happen in normal countries as central banks do NOT give money away to the government or society, and plus, if there is a surplus of money inflation appears. But the money supply is affect by money velocity. If the saudi and other emir families just store this money secretly without using it, there is no way for the market to know, and depreciate the arab rials on the forex exchange rate with the dollar.

Am i missing something here?

What's meant to be the point of printing large sums of money without using it in any way?  

If they are exchanging this currency for US$, then the currency traders will notice the excess supply of arab rials and adjust the exchange rate accordingly.
