In light of recent events and for the purposes of making sure we are not just sheepishly following the crowd off a potential cliff, I shall impose this question as a devil's advocate:
Why we on GAW are certain that gold standard is going to solve all of our problems? Also why are we certain that a return to the gold standard is Q's plan?
I am fully aware of Q's "Gold will end the Fed" quote, but it does not explicitly say that the White Hats will abolish the Fed and bring us back to the Gold Standard. It is probably a simple statement of facts like saying the Sky is blue and the sun rises in the east.
Gold does not corrode, degrade, nor break down from exposure to nature. It is also the best conductor of electricity.
Apply gold plating to anything, and that object becomes more valuable due to the fact that it can withstand exposure to nature better, and last longer- not simply because it's shiny and pretty. And everything electronics loves gold for the same reason, plus its superior conductive qualities.
That means its uses are near infinite, and it will always be a high demand material, and hold its value based on the law of supply and demand.
There is also the fact that it is physically very difficult to counterfeit. The only other metals that have the same or higher density are often just as expensive to obtain.
