I don't think it moves forward the liberty movement forward at all. It is extremely likely that almost everyone watching already agrees with him, and people that already agree with him watching him 12 minutes a day will have no effect on anything. Listening to people doesn't change anything if you already agree with them. In fact, it just makes you stuck and nothing changes, but perhaps you get disillusioned that you're doing something to help, even though you're just watching someone on a computer screen for 12 minutes a day.
Sorry if this comes off a bit rude, but I think its important to expose these sorts of things that we hear all of the time for what they are. We don't want to believe this is true if it really isn't.
