First off, Bitcoin is only pseudonymous and not anonymous by default.
Second, what the hell is that linked video? It started off with "on behalf of the entire team at Satoshi Nakamoto". That's an auto pass for me.
Bitcoin is not anonymous. That is why bitcoin mixers are so popular and there are a lot of Bitcoin mixers on Bitcointalk too. But I think that Bitcoin has a big future because people need it. Even now when there is a world financial crysis Bitcoin is more stable than fiat and stock market.
Another important thing is that if anonymity wasn't necessary or part of Bitcoin goal, satoshi wouldn't have used tor and we probably would have identified his coins by now. Same as people developing auxiliary anonymity tech for Bitcoin. If anonymity is not necessary developers won't be in hurry to build anonymity tech.
In my opinion, It's possible to buy bitcoin today and nothing man-made will be able identify who bought them. Very few can do this I guess
