There is buzz about the prospective of governments and banks accepting crypto or creating their own for its mass acceptance.
I don't think this is even worth acknowledging, as all of the present and future innovations are going to come from the private sector. Governments are just responsible for damage control, do a God-awful job for the most part and have never achieved true democracy.
In the past, people relied on governments and banks not because they're "governments" or "banks," but because they provided security.
Once AI, blockchain, and improved means to use crypto provide even better security than governments and banks ever could, whatever they do will be irrelevant.
Even if I will not care about such a development, most people will care especially those that do not really know why governments and banks have the monopoly of printing money in the first place, as you say they got that monopoly to bring confidence to the people and security that their coins had value, but now that a new way has been created to do exactly the same thing and it can be done with greater reliability then we do not need their control anymore.
