Slowly government's that are against the use of bitcoin will start using it. As a beginning we've seen statement from the Russian government. Previously there were more governments that imposed ban on bitcoin with punishment and penalties to be paid to the government. Even by that time people from those countries keep on using it. The technology growth always has got a set of people supportive to it as well as people standing against its usage. Later after hard analysis they realise the good in it. Same has been taking place with bitcoin right now.
The US has to follow suit. There's much to hate about my govmnt (Argentina), but they have progressively made more and more efforts to include decentralized solutions (David19 comes to mind, as well as a Koibanx led effort with the argentinian central bank), all of this is to say, admiting is not enough, acceptig that decentralized efforts is the future and looking for ways to implement it, that's what needs to happen in more places!
