> What about your idea regarding inflation as a way to avoid concentrations of wealth? (the idea I quoted and I replied to). That one is unsustainable.

You're free to discuss the facts I've pointed out, instead of going off on a tangent with a non-sequitur regarding Argentina's hyperinflation. It's undeniable that stockpiling cash out of the economy has a deeply negative social, economic, and even fiscal impact on a nation. Inflation provides an incentive to actually put the money to use, and interest rates for the most conservative investments, like risk-free bonds, are then used to provide incentives to couple investments with economic cycles.
