now they see BTC is an enemy of central banks, and because they are enemies of central banks as well, perhaps they'll realize that Bitcoin is an ally.
Yes, undoubtedly the "enemy of your enemy is your friend" is the best line of persuasion with hard-money people who are skeptical of Bitcoin due to lack of tangibility.
I predict the US Fed, IMF, and major economists will, in 2013, put out papers on the Bitcoin topic. Central bankers and academics have lemming characteristics, and many will jump onto this bandwagon now that it's been legitimised as a "respectable" area of research by a "serious" institution. Floodgates have been opened.
It's a beautiful virtuous circle for Bitcoin, and a beautiful vicious circle for government fiat. The more they talk about Bitcoin, the more acceptable and established it becomes, the more it will undermine and expose them, and the more they will have to talk about it.
