I didn't ignore anything. As I said, deflationary currencies encourage savings. People held on to the money they felt would maintain its value, and spent the inflationary money. It's Gresham's law in action, and pretty much all economists agree it's a typical dynamic. Nothing about my comment ignored the facts of what I responded to. I simply interpreted the facts accurately and pointed out a subtlety that you were not perceiving.
The fact is that the US experimented with going off the gold standard throughout the 1800s, but overall stayed with it, and we experienced growth while the purchasing power of the dollar, long term, went up by about 40% over that century.
