A free gold coin standard will take care of itself, thank you. That's precisely why statists have always hated a gold standard-it's outside of their control. Thereby severing the last link to gold and setting the stage for future massive growth in government debt and inflation. Even bad guys can do some good. A floating currency system invites such upheavals, creates a whole new type of financial instrument to speculate in, and permits politicians to manipulate entire economies.
Gold is a narrow defination of wealth.
Mankind has affirmed its attachment to it over all of recorded history, and continues to be valued today. Here at last we agree. There was a hyperinflation caused when the looted gold of the Americas was sent to Spain. But it's important to note that this was an one time occurrence and could never happen again. You are way off base here, unless you want to consider pre-1929 England an agricultural outpost.
