This is clear you don't know much in crypto-currency, or internet at all otherwise you would have not taken the bitcoin as the best choice to anonymize your transactions! There is much better choices ! By the way, terrorists use oil and dollars to finance their war, should we prohibit them ? That way they will not be able to finance their war right? And as for internet, if there was a central body governing the internet, it would have become crap very quickly ! But thanks to Tim Berners-Lee and the people who developped internet from Arpanet, that's exactly not what they wanted from the start !! If internet was centralized, it would have been distroyed very easily. One head to cut off! On the opposite, the fact that there are so many nodes in the network right now, in a complete decentralized way, makes it completely fault proof ! THAT was the point of the internet... Internet is about freedom, communication and opening to the others not the opposite... There can be bad things, but it has delivered much more good than bad (in my humble opinion)...
