Gold has lots of industrial uses more all the time but it'sAlso an undeniable currency or the only thing we can use as a safe haven against paper We need paper as its so fluid and accepted world wide A country's currency has to have a proven trak record tied to the culture as well. That's why people will accept neg int in say Japan they culturally are known to be solid and no mater what they spend people know they can be trusted and culturally would always try to improve no mater what.
