Actually funny how that works.. Nobody had to announce or validate Gold as legal tender... That whole episode started when fiat was introduced. Just another way to force people to use fiat. Now "sheepy" humans have become so used to the abuse they think money needs some governmental approval.... No it doesn't. And that is one of the many things turned upside down in current society ! Seeing all that crap doesn't make things easier, but without realizing it nothing will change for sure.
