Hey there, I'm afraid there the article comments module is an all or nothing feature. If anonymous editors are permitted to edit the wiki then they are permitted to use the article comments module, likewise with the forums, talk pages, and message walls. Manipulating the article comments in anyway as to remove functionality, such as hiding anonymous comments, is also against terms of use. So I'm afraid that there is no way to turn it off for non-registered users.
