We should start the campaign in favour Of Bitcoin.
The bitcoin campaign started many years ago and it's still ongoing to this day. I think there is still a long way to go before governments can get their shit together and allow bitcoin to co-exist with their paper money. What could possibly happen is that people may be forced to give up their privacy due to laws that will require establishments to enforce some kind of identity verification before accepting bitcoin payments. An example is asking for an ID before giving receipts or something similar.
It will be a long way before bitcoin will be accepted and regularized in different countries, as what you have said, there will be a lot of information verification that will lessen the privacy of one consumer, and we cannot say that everyone wants that. Besides, bitcoin is still on developing stage where we invite people who are interested in it. Everyone is used to have transactions and exchanges in fiat currencies, so it will not be easy having a brand new currency that will be used in our daily lives.
