Except the bank interest still doesn't beat inflation, let alone the rate of M2 increase. Chase offers 0.1% on savings accounts right now, which is useless.

I also long for a system where everyone holding the currency isn't implicitly taxed through dilution, forcing them to passively invest, creating bubbles... and still being taxed on the "gains." These passive investments are more about stashing wealth in something with a limited supply (stocks etc) than about the actual business they're investing in, making them not all that different from BTC.
