Certain governments might issue a ban at some point in the future when Bitcoin is becoming too much of a problem that can disrupt their economy, but at this point we don't have to worry about that yet. Mainly because of Bitcoin being just an alternative currency/investment tool. That's why we must be happy with how Bitcoin is right now.
That must be true. When our governments will be thinking about regulations on bitcoin, bitcoin would have been developed as a most adopted payment system, probably everything will be available for bitcoin payments. When we are able to spend bitcoin directly for our life's needs, the never need to worry about any regulations.
Poor country people do not need to worry any such a ban. They will be able to use bitcoin all the time without worrying about their government's opinion/regulations on bitcoins.
