If the subject of the wiki is of interest to children, then Staff will disallow registered users without community discussion.

If the problem is mostly with page creation, you should consider only restricting page creation to registered users and still allow anons to edit pages, since reverting an edit page is something anyone can do, unlike a page creation.
