just make an ounce of gold worth $25,000 instead of $1750 and it works. or 50,000 dollars. you get the idea.
No it doesn’t. The increase in the money supply would be dependent on how much gold you are producing. The existing stock is how much you already possess. So countries with no gold have no money? The US is in the top five producers, but only produces a fraction relative to the GDP. China is the biggest producer, but has a small stock of gold. Canada is a big producer, but owns no gold. Invade Canada to increase your money supply. Also, at the numbers you quote, between your house and the nearest Starbucks, there would be 3 dirt hills as people dig for the metal.
