Governments could have criminalized it at any point, they can criminalize it now, and they will certainly criminalize it in the future if they feel a need to do so (unless this thing gets used by >1% of the population which I'm willing to bet money against.) They didn't because they didn't want to. If they wanted to know who created Bitcoin in order to "torture" them they would have found out, at this point we know how good they are at this sort of thing; also, if they wanted to "torture" prominent people behind the Bitcoin software there was never a shortage of people with known identities. That he didn't pay his taxes seems to be a separate issue.
