To me he sounded supportive of one of Bitcoin's themes, which is to automate the inflation according to a fixed set of rules and take it out of the hands of mere humans.
However, I'm not sure if Selgin fully accepts that the concepts of "central control" and "guaranteed scarcity" are simply irreconcilable. Computerising the FED would just be a fancy gimmick if banks could still exert the same power by controlling lending rates. The entire hierarchy would have to be automated -- so much for his wishful thinking about reducing regulations for his banking buddies. It boils down to 2 rational options: have the whole system nationalised and centrally controlled, or have it decentralised and uncontrollable.
