I agree. Now about the second question, "for whom?" Was it really meant for a common man too? Or just for the people with lot money and who don't want to pay taxes or involve a third party or even don't want to let anyone( or government) know about the sources or amount of their income etc.
Who knows Satoshi could be hired by a drug lord or a mafia king to make this and everything what we see is just only what they want us to see.
Are you really serious with that thought? I could accept that it could be created by someone in the NSA, CIA or DARPA but drug lords and the mafia? There is too much harebrained thinking in your comment. For you, did it come to mind that the main reason for the creation of Bitcoin was to disrupt the banking system and not to hide wealth from the government?
If you can accept NSA, CIA or DARPA why not a person with billions to hide from the government and make transactions freely as well? Won't this theory make more sense?
