I don't think it is possible to ban bitcoin, if it was, it would be banned already.
That was very impossible to happen but if the bitcoin is we will be banned, that will the worst moment for all of us, specially for all of the users of bitcoin, because bitcoin is part of our daily lives, bitcoin is helping me and helping many people to have or to earn many money or profit so if bitcoin id we will be banned many people will became dissapointed.
