You get it, swombat (at least in my humble opinion). Thank you for posting that, I hope that it helps some people understand the distinction between currency and assets that produce returns.

edit: Just thinking further on it... I tend to approach things by thinking of pathological cases. In the case of a deflationary or flat currency, I think currency hoarding is a rational response economically even though it's unproductive and leads to high concentrations of wealth. On the other end, inflation that's too high will lead to an economy that is very illiquid and prone to solvency crises. There is a high incentive to minimize cash on hand and maximize debt. In my lifetime I've really come around on the value of a managed and low inflation to having a productive society.
