You can't send robots to Mars by basing your endeavor on Ptolemaic model of the universe. You can't use decentralized, limited-supply currency based on archaic concepts of debt money and interest. With the help of Ripple, maybe.

This should not be such a scary thought. Finite, mathematically defined and scheduled supply of currency.

You need money - go earn it. You need something - spend it.

You want to sit on your ass and do nothing, while charging others the interest - go fuck yourself.

You don't want to spend your coins today on something you need, because you expect tomorrow you'll be able to buy more - fine, die an old, poor, sorry idiot with pockets full of coins and empty, shallow, wasted life.

The economy grows - the value of everybody's coins has increased. Perhaps people with archaic btains start spending less, hoping for even more increase in value. The economy shrinks - the value has decreased.  Archaic brains panic spend. It all self adjusts. Those who understand don't care - they live their lives, and use Bitcoin. Everybody in the same boat, plain and fair.
