Um gold standard isn't exclusive from central planning...
The price of gold from 1995 to 2011ish went up 466% ish, think of what that means in terms of deflation. Inflation was like 9% I think.
It excluded if you're using a true commodity based currency. Not gold backed paper...
And really, going up 466% in relation to the dollar means that there are 466% more dollar bills today. That tells you nothing.
