He never did, but he sure lingered on the fact that bitcoin could very well be a great contender for a digital currency, which bitcoin is used today. From the quotes and posts you linked in here, it clearly state Satoshi's oversight of what's to come given the nature of his creation. Free from banks, anonymous, deflationary and of course, peer-to-peer, this is what he really had in mind and not overthrow the current financial system that we have right now.
Whatever he created, it's working real good and we are reaping the bemefits off of it.
But unlike this what I think is that most of crypto and bitcoin enthusiasts actually want it the other way. They are keenly focusing on how to inject cryptocurrencies into the financial system of countries and pave a way for mass adoption. We all know that governments would even not allow bitcoin as a secondary currency or a means of settlement alongside their national currency due the anonymity it has.
Moreover, most of the people around the world don't really bother about P2P they don't have much of a problem with an intermediary in between. So basically bitcoin would remain like this only even for years to come?
