I do not agree. It's not because my door does not have locks that you can feel free to enter. And vice-versa, it's not because there are locks on a door, that you don't have the right to try to enter...
Your analogy is not exactly correct.
With an iDevice, this is someone else installing locks on your own door and not giving you the key, and they monitor who is allowed into your house. Even if you wanted the key they won't give it to you nor let you replace the locks.
