Without Bitcoin, monetary policy will always be somewhat centralized in the hands of a select few. However, Bitcoin allows for truly free monetary policy free of force or coercion. Why? Because unlike all other types of money before or after it is truly abstract, playing on a public defined set of rules.
No longer would a centralized power use Fiat for a currency it manipulates completely in the guise of monetary growth, or avoiding deflation. And it is clear to us here, that these manipulations whether in changing interest rates or infinite borrowing, always create the problem they were created to solve, playing in a vicious spiral of taking ineffective - or rather hurtful - action to solve a problem created by the printer itself.
Bitcoin is a freemarketeer's dream, and it is a hopefull person's dream too, giving power to the powerless. Fortunately for us, it's real.
