Hrm. Interesting hypothesis. I do tend to agree that there must have been a group who worked together to come up with Bitcoin. However consider it was also in response to (or coincided with) the housing crisis in 2008. The concept of a decentralized currency that couldn't be tampered with and controlled by a central authority was born then.

So the question of whether a government authority would actually want to create a system that would reduce their ability to regulate and control is a bit hard to believe. Looking forward to part two!
