I can only say that if I was the one in the position of extraordinary power (as our current rulers from the shadow are), looking to overcome the market segmentation and rule the whole world, inventing a digital worldwide currency and hiding its "inventor's" identity would be the most logical course of action. To be honest, if they really did do this, it's a truly work of art move as they made such an anti-authority guy as I am love the bitcoin. But even against all the odds, I am still hoping the romantic, rebellious version of the story ("Satoshi Nakamoto the hero outsmarted the powers that be" and all...) is how it really is.
I recall from Faust about Mephistopheles that he intends to do evil but his deeds always turn out to cause good. Perhaps it's the case with Bitcoin? That Illuminati invented Bitcoin to execute their evil plan but it goes terribly wrong

Fact is that we need to have a store of value and a means to transfer value. In that sense Bitcoin is definitely the lesser evil.
