...to allow people to withdraw their coins?
The government doesnt opperate on a level of care like that. Nobody really has the power in the government to slow down any process. Once "bad" actions have taken place its all hands on deck to make things "right".
There is no "right" in criminal activity. Do you think that government will allow people to withdraw their bitcoins? After all they know people used it to buy illegal stuff? What kind of government allows criminals to 'take their money and go home'?
