Protections have three levels: By default, you have to have an account in order to rename a page, but to move it to a new name without leaving a redirect behind, that takes Admin or Content Manager rights. Normally it isn't a problem unless the page is renamed to different names twice in a row. Then an admin has to move it back.
 * Unrestricted and you don't have to sign into an account to edit.
 * Autoconfirmed, which means you have to be logged into an account that you've had for more than four days.
 * Sysop, for those with Administrator or Content Manager rights.

It would help if there was a protection level that was in between the last two, maybe based on number of edits on a wiki so you knew if they had made more than that, they could be trusted on pages that were controversial or targeted for vandalism.

Regardless, before any page is protected from editing, you have to weigh the need to curb bad edits versus keeping people locked out that might want to edit.
