In my opinion opening and closing threads is a moderator privilege. When someone wants his thread closed, he can report his thread/post and request it. It should be closed immediately once a moderator notices the report.
The only places where I would allow users to close/open their own threads are in a WTB/WTS marketplace and in their personal blog. If by chance a blog entry or a marketplace thread is in violation of the rules moderators can delete them or move them to an internal trash can forum.
