But those who think that Bitcoin was created by "the gov" or "the CIA" or whatever (mostly, U.S.) agency may think that it was so revolutionary that it needed some year-long secret research by multiple people, like when the nuclear bomb was invented, when what was necessary was mainly an "Eureka" moment to combine the correct parts of the puzzle.
Nobody is saying that. In fact it's the exact opposite: the CIA or NSA could have easily, as a small side project by one full time employee, invented Bitcoin. They could have done this as an experiment, and then it got out of control.
I also do not believe in the honeypot theory. Honeypot to catch whom exactly? What would they achieve with this? Cash is still much more anonymous and fiat in general is much more popular for most criminal endeavours ...
Crypto has been used to invent an entire new class of crimes. Before crypto, terrorists did not shut down a hospital and then demand several hundred pounds of paper bills. That would simply not be practical. Crypto has made cyberextortion possible and practical, to say nothing of money laundering, tax evasion, and other crimes Bitcoin enabled (at least initially, until chain analysis became common).
