Can't say much for the guys reasoning, however he kind of got a little bit lucky in that btc is vulnerable to being taken over by the power elite. In conjunction with the current police state and internet spying and data mining, it's positively anti-anonymous. And a corporate/government 51%+ mining cartel is pretty much certain once the block rewards dry up, if it's mainstream enough at that point.
I doubt there's a need to get an rfid implant or get "666" tattooed across your forehead though.
I have considered this a bit, isn't it miners who decides what goes in blocks. As such certain large organisations who got potential to invest in effective hardware could control most of transactions? Basicly they would just do "approved" transactions, and leave rest up to other people. Or even some cases fork the chain...
