That's what I'd do. The off-topic section would have no place on the "front page". I'd also do other steps to make an "off-topic" section less of a problem...

Have a user setting so that monks can choose to not see such in Newest Nodes and have it set such that Anonymous Monk does not see them. Make Super Search default to not searching such. Have the "off topic" "section page" (like Seekers of Perl Wisdom and Meditations) only show titles not the contents of root nodes. I'd be tempted to not have a "post new off-topic node" form, but I think that wouldn't be helpful. Probably just not allow Anonymous Monk to post new off-topic root nodes (make it a level 4 power but don't advertise that). Charge 2 XP for posting an off-topic root node or having your node moved into the off-topic section... (:
