Government is already troubled by the acceptance of bitcoin (rather crypto currency). The government might try and make it difficult for bitcoin (again, crypto currency) to really be a widely accepted currency but I think it's acceptance is inevitable.
People love decentralized currency, many might not know what it really means, but they just like the idea of the power being in their hands.
Same reason why Democracy is so predominant, most people don't even care how beneficial it is or isn't.
