If a genius mind invented such a game-changing technology, it doesn't mean it was part of the CIA or any other government entity.
Bitcoin was probably just an experiment, Satoshi probably never thought it'll get this far and maybe it was not even what he wanted. If BTC would've NOT been an experiment but a cryptocurrency meant for the everyday use, I think he would have written a completely different code. On the other hand, even genius minds sometimes make mistakes. Genius doesn't mean 100% perfect. Look what Satoshi said in early 2009 regarding the scaling of Bitcoin (source

The existing Visa credit card network processes about 15 million Internet purchases per day worldwide. Bitcoin can already scale much larger than that with existing hardware for a fraction of the cost. It never really hits a scale ceiling. If you're interested, I can go over the ways it would cope with extreme size.
By Moore's Law, we can expect hardware speed to be 10 times faster in 5 years and 100 times faster in 10. Even if Bitcoin grows at crazy adoption rates, I think computer speeds will stay ahead of the number of transactions.
My question to everyone saying it was not just an experiment is: if that's true, why did he ask coders for help? I understand BTC is open-source and all that stuff, but if he would've considered it perfect, there would've been no need for help from his side.
However, this is only a kind of speculative thing. Unless he comes back and answers every single question, we will only predict the answers but nobody will ever know which one is true and which isn't. But I do not think he'll ever come back again. He left us alone with a reason. Remember what he said regarding WikiLeaks (source

It would have been nice to get this attention in any other context. WikiLeaks has kicked the hornet's nest, and the swarm is headed towards us.
He was afraid of something, or hiding from somebody. I wouldn't deny the fact that he is most likely still around here on our forums, maybe even reading this thread though.
