You can have privacy and security, you just have no guarantee of one just because you have the other. Cookie tracking is like wearing only a towel at the beach. Under the towel, you have privacy. But browsers suck at security, and so many websites can still walk up and yank off your towel, exposing you. Security would be locking the towel to your body with a padlock. I'm not aware of browsers implementing strong security mechanisms for user data, so I'm pretty sure any privacy gains you get are just another towel.
