No, dont make governments accept bitcoin. I think it's impossible that government accept bitcoin, because bitcoin is annonymous, they cant track your identity, governments do not like anonymous currency and do ot do anything to device a tool for carry on with that type of currency and bitcoin is not going to deny that feature of itself as it will then destroy the concept of cryptocurrency
no it is not impossible, i think every thing is possible in this world. although in present time it look like difficult but i think in future when bitcoin will become more and more popular when the users of bitcoin will increase more and more,then i am hopeful that the government will take a very positve stop about bitcoin. and hope that they will consider bitcoin as legal currency, but there is no doubt about that fact that it will take some more time. because the users of bitcoin are still very low.
Yes you are right it is not impossible and as you can see the steps of japan which are going to regulate bitcoin in their country officially from the government side. In the same way other countries will also start to take the same steps when they feel the importance of it in their state.
