Crimes happen not because of Bitcoin but because there are criminals (or would be criminals until they get caught and convicted). Blaming Bitcoin is like blaming the gun and not the guy who pulled the trigger. Though you are right, at least to a degree, that governments don't care and more often than not just don't want to deal with the real causes of a problem
I have to agree with that
Government (any particular government, for that matter) seems to be the worst problem "solver" out there. Instead of dealing directly with the root of the problem, they seem to be more busy incessantly fighting with symptoms. I guess if it were any other way (and any other way would still be a better way, lol), people would start questioning why there are so many slackers and shirkers sticking around in the government. Rephrasing Winston Churchill, we can always count on the government to do the right thing after they have tried everything else
And that is why we most of us here in bitcoin community don't agree to have a government intervening with bitcoin. Because it would be a bad news for us if they will apply taxes and some fees to every transactions we made using our bitcoins.
