I 100% agree with you. Bitcoin was clearly a government creation. Why otherwise would the developer want to stay so anonymous and also never touch his massive wealth in Bitcoins. In addition, the perfect code also implies that a very skilled team was behind it. (I certainly don't buy the recent BS story of AI developing Bitcoin.) Don't forget that Satoshi Nakamoto roughly translates in Japanese to "Central Intelligence" as well.
I also expect that is was no coincidence that Milton Friedman "predicted" a digital currency similar to Bitcoin. I assume there was a government think tank, including Friedman, conceptualizing it much earlier on and then building it in preparation for the right period for release as you propose.
