Good point.IF a currency is backed by gold, then a holder of a currency has a right to demand for gold. Even the Swiss terminated in in 2000. Currency is relative and higher currency value will impact export.
Everyone chiting on USD or Treasury are conveniently forgetting Euro/Yen/Yuan/Ruble (lol) are just pieces of electronic paper as well.
Golden Rule = He who has the Gold makes the Rules. Substitute Biggest Army for Gold nowadays. Until that changes USD is going nowhere.
