It prevents users like Alienmonkey from abusing it when he goes to sleep, just so he can reopen it when he wakes up.

Also deters people from making one post and close the thread so they can put their opinion, however stupid it is, out there and still have the last say in the topic.

By deleting the thread, nobody can read what is said. But deleting threads is still the cheap way to "save face" when discussions go against the original poster.
