The Gold Standard Allows Bankers to Exist
First you start off trading gold, but quickly realize that its heavy as shit.. So instead, you make a paper currency which supposedly now represents the gold.. And sooner or later we all know what happens next.. The bankers get bored sitting around all our gold and figure out a way to steal it!!
Why not just create a currency like bit coin? Instead of making the same mistake society has made over and over again, we could use the technology we have to bypass the bankers!!
