It's been a while since youtube started restricting access to video that have been flagged. I don't remember when exactly but in 2009 there were already videos explaining how to circumvent this "feature": http://www.youtube.com/watch?v=lUkrX7PZNok http://www.youtube.com/watch?v=lUkrX7PZNok Then there are the video you can't watch from third party websites and from certain regions and so on. It is an improbable possibility that google will require to be logged in to watch youtube videos, but it's still could happen one day.
