Money is conceptually very much tinged with psychology. One can use any object as a common medium of exchange, history demonstrates this amply. Either this Smets character believes in his own institution's BS too deeply to accept this fact, or he understands the psychology at play and is attempting to manipulate the way that the public perceive Bitcoin's value as a type of money. He's either a useful idiot for the central bankster monopoly, or a highly machiavellian piece of work.
I am sure deep inside the man believe that whatever form of money that does not come from them will always be bogus and not worth exploring with. While i understand all of these warnings about how we might lose a lot of money with Bitcoin, the warning should also be pointed to the very institution he is heading. This is indeed quite ironic. We should be warned that Central Banks are not anymore working for the benefits of the people but themselves. I am sure that history will proved how fatal had been our common belief that bureaucrats will always be there for us.
