Why is a gold standard sometimes necessary rather than using paper fiat money? Group of answer choices Actually, it is never necessary to use a gold standard. All the government has to do is declare that paper money is the real money, and that always works. Because gold is real money with real value, while paper money is not. Because psychologically, people will now transfer the value they believe gold has over to the paper money. Because sometimes paper is in short supply and thus you have to use something else like gold instead
