I still shiver at the idea that most people don't give a damn if somebody will have a nearly unprecedented level of power, as long as they can have a little slice of the riches. That let me think to those disgusting orks doing all they can to let lord Sauron have the world, as long as they are in the winning side. No matter if the world is going to hell.
satoshi may have 10% of the currency supply but it will only become as valuable as you are making out if bitcoin manages to break the current monetary cartel. so we would be replacing a group of people with the ability to print an infinate amount of money with someone who has 10%. clearly an improvement and the 10% is his reward for so dramatically improving the situation.
