Second, it is easier to win if your competitor lets you win. Build your opponent a golden bridge to retreat across. If a governement can take advantage of crypto (and I already explained it can), make it so that this is a mutually-profitable agreement. Hatred does not go far; negociation goes much farther. Hey, I'm French, I know what I am talking about, we have an A-grade in Stubborness and Stupidity (Africa, Indochina...) whereas the British were much smarter.
Governement wants money and control. Let him do it whilst allowing anyone on an individual basis to opt-out. If we create the tool, it will be possible. If we let the government create it, much less.
