You do have a point but I think this is bigger than the Internet (or will be). Bitcoin most likely won't be the end result of digital currency. Something else will take it over. What really needs to happen is have some integration with the banks and the cryptocurrency network. That will be the true winner at the end of the day. Something where you CAN store in banks as an option but pull it out and store on your own if needed.
I agree, as Karpelles said just before stealing 500m US Dollars worth of BTC: "Bitcoin was just an experiment"
BTC is the entry level or introduction to the world to digital currencies let's say, nothing will ever stop the central banks to change their monetary system unless they rule it, or create it.
So the experiment could be BTC as Karpelles said.
Once they decided is enough then they will merge some other types of cryptocurrencies or digital money into bank accounts.
And regarding Satoshi all i know is that he came up saying he does not know anything about Bitcoin, well some satochi nakamoto somewhere in California.
