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.
It matters. We need their consent on this for they are the one handling/regulating things economically.

They don't necessarily need to integrate bitcoin and cryptocurrencies in their infrastructure, but having them approve the existence, trade and exchange of bitcoins and other cryptocurrencies is a huge plus for the confidence of the masses who would want to try it out.
I also believe in this statement, if they allow bitcoin and not use it that's fine. They are not forced to. But as time goes by I think they will still use it. They will need to cope with the advancement.
