Short term, It does matter what the Fm of a country says !!
Long term , Its safe to say most governments will be too late in the game to take any drastic action. Leave alone all of them coming together, to act against this revolution. They can make all the noise they want, fact remains, no country alone or even few group of countries can contain crypto.
They can try, only to later adopt it.!!
They will be too late in the game to curb this revolution.
