Your take on how this influences policy makes sense. When I read the whole thing last night I did get the impression that they were scared. Maybe central bankers are starting to perceive  the real power they are confronting.

The Distributional Consequences Of Bitcoin

IMO first steps will be higher taxation of btc gains like Italy is implementing now with a rise of cap gain taxes from 26 to 42%. Keep in mind that the members of the Eurozone are fighting against their fiscal destruction, a recession and capital flight that is concentrated on the EUR/ USD pair. I still think that Brussels/Frankfurt/Davos don't get the power BTC will be setting free when we see real adoption in Europe. Until now it really doesn't play any important role.
