This is nothing new, it has more than a year that i read that document, i think they will do the fork when they have enough Bitcoin, its a matter of time. 
Law enforcement will be with them. 
And it's a easy move for the establishment to do it, mining is already centralized, they can censor ligthning transactions already, who don't comply will not be able to transact freely like nowadays. 
Who needs a CBDC when they can program in what already exists?
