You were not clear. I didn't say proven to not tend toward greater human prosperity, I meant only to say that this ideal is not based on reality, it's not necessarily the best issuance schedule for hard money, if given the choice.
Rothbard's What Has Government Done To Our Money or Mises's The Theory of Money and Credit. I'm still not finished reading them myself but they clarify terms and illustrate the general effects of these things.
The burden is on you - if there is one at all - to demonstrate why this would lead to greater prosperity than a money that tends to deflate.
