Good post but I think you are concentrating too much in the way things work now, if you look at the past you will see that the asset which was selected as a form of money was the one that had the best characteristics, this is why in ancient times gold and silver were chosen by many independent cultures as their form of money, but this has been distorted in recent times, bitcoin is just a way to try to go back to those times in which the superior asset became dominant.
