well john im not going to make the claim that bitcoin will save us from wars, i like to think that it COULD, that it is possible. But there is a difference between gold and bitcoin and that is bitcoin empowers individuals to trade globally. That is we had this wonderful technology called the internet which was limited in its effect because we were forced to rely on centralized institutions (and so state influenced) to transact over it. Now that we have an anarchic currency like gold that can be used over the internet it could begin to make the state obsolete. Gold has no such properties because its only useful for local trade, thus there is no expectation that it might begin to tear down political borders like bitcoin potentially could.
