The price of gold can rise and fall, but you can't print more gold to temporarily float an economy, at the cost of later, catastrophic inflation.
Gold backed currency is the most stable, most immune to inflation, and most representative of the actual value of an economy. The fiat system (described in all its horrible failure above) can never even begin to match the stability, honesty, and genius of the gold-backed currency system.
I like you RH. Kudos. I had a friend from another forum ask me about this a few days ago, but I didn't have the benefit of your linked examples to help the explanation.
