When I learned about micro and macro economics at school and specifically about money and its circulation, of course the state must have gold reserves to guarantee fiat, when gold reserves are abundant then the state has the power to print more money so that it can make the people more prosperous.
What proof do you have about that, I understand that gold reserve is important to know how rich and influential a country is and fortified the economy is like US for example with the highest gold reserve in the world. But does that mean that any other country that has no gold reserve won't print there fiat like we know some countries don't and yet they print money and exist as a sovereign nation. So what is the proof of your idea.
