It turns out that cascade protection only works for protecting all articles from edits by non-admins. I could add a policy like you suggested that prohibits unregistered contributors from editing, but it is unlikely for unregistered contributors, especially vandals, to look over a policy before editing. It will also put another task on my list of having to block every single unregistered contributor as soon as they make an edit. Does anyone have a better suggestion?
