The governments should actually be so happy with bitcoin that they can recieve all there illegal funds with minimal trace.
Here's the minor flaw: the most upper echelons of government can conduct their criminal activity through the incumbent financial system no problem. And I say minor, as you've still uncovered a useful point. The lower down the food-chain of government cronies that you descend, the less their access is to the various mechanisms that allow the big fish to abuse the regular system. It massively empowers low-level government criminals, the type that will never make it to the high ranks and know so. So it's a fight between two different criminal enablers: one that's exclusive, based on status and social circles, the other that's fully egalitarian as long as you have the technical ability to use it. I know which one is a more powerful force from that description.
