this is complete crap! I'm Portuguese and that island is basically a joke... the guy thinks he's a king of that place, or something like that, lol! And yes, nobody lives there basically, and there is no commerce... no real places to use Bitcoin, to make it circulate.
as discussed on this forum quite a few times, Bitcoin can't really be a national currency but it can be widely adopted... But on places where more than half a dozen people live and where there's commerce

Maybe you're right, Bitcoin is decentralized and freedom, not a government will start them can not control the money
