I think you point out well how the competition of currency which has been created with bitcoin will lead to the evolution of ideal money.

In personally doubt that central banks will play much of a role here though as I think other cryptocurrencies will simply be more powerful.

Kings could have run their courts like a company, yet few kingdoms exist and if they do, they have lost most if its power.

Likewise I think, by taking away the monopoly central banks enjoy, bitcoin will make central banks look useless in the near future (like one or two generations)
