It is not all wrong, however i beg to differ that a currency 'guarantee' only exists if people agree on its value.
Gold is certainly a standard, but more is being found every day, also after WW2 you could not even buy a loaf of bread with a bar of gold, seems the farmers did not agree to the value when bread was scarce, and needed to survive.
If enough people agree on a currency, and be it toilet paper, it is worth what people give for it. And that depends on time and general cirumstances of trade.
