You don't need access to cookies you didn't create to do cross-site tracking. Think: Disqus or Facebook comments at the end of articles, which used to be pretty ubiquitous. You'd be logged in and able to comment on any website using a cookie set by Disqus or Facebook, so you wouldn't have to log in or register on each individual website. This Total Cookie Protection will break that. Your Disqus-set login cookie set on site A won't be visible when you're on site B, so you won't be logged in to Disqus there.
