The government understands bitcoin more than you do. They have also known the potentials of bitcoin. They have known how fast bitcoin will grow if given free hands. They also know that their strongest weapon  (centralization) is threatened by the existence of bitcoin. This is the main reason the government does not give bitcoin free hands to operate since they are unable to control it.

If the government has not found a proven and a reliable way to monitor and tax everyone using bitcoin, they can not be at peace with bitcoin.
