What they can do though, is to attack Bitcoin due to all the non-reversible scams & hacks, bad PR, price fluctuations etc etc, and say "look, we will give you a digital currency that is all that Bitcoin was and safer, more stable due to government backing" etc etc. We give you safety and stability and we take your freedom kind-of-deal.
As long as we have a real choice...
The masses would take it any day btw with some proper conditioning. The problem is not the masses, it's the states/countries. Why give monetary control to an outside source? It is financial suicide if a country can't issue their own national currency and instead have to borrow it from a central bank which is elsewhere. So they might entice the countries by saying "we'll erase a large part of your debt if you accept this new currency" and that will give the puppet-rulers installed in each country a disguise of "legitimacy" for betraying their countries and handing over monetary control to the over-state of the global central bank.
sadly, this seems a likely scenario.
The idea of the nationstate is failing. The governments of the world are being corrupted by the men running the monetary system. It's a kind of fascism basically: the corporatocracy and governments collaborate to control the people. And yes, I agree, it's a possibility we'll end up with "one western central bank". Might be spawned from the IMF. They'll issue (or likely reuse the SDR) a new fiat and back it with some non-existant gold for good measure.
Good thing we have crypto to fight back.
