We see such problems every once in a while but I do think that you have to understand that it can go without any county of any government. Complete ban is not only impossible but not needed. There will always be people and countries supporting Bitcoins and government can't sentence thousands of millions of people to jail because they used Bitcoins in the same day, they won't have enough cells for that , haha so just keep using it and fight for it.
Ban is only implemented if the public decides to go with it.
But is it really going to be thousands of millions of people or will it be a few hundred people in each country who are willing to root their phones to install apps, since all the wallet apps will be removed from the app stores? Haven't we seen how easy it is to control the public in every country?
