Again, if you want to say that you need to make the class as terrible as possible so that people drop, then just say so.
I hate to make this request, but I need half to 2/3rds of the students to drop the course. I'm hoping that you will still be able to learn a lot from the class -- but I need to find a mechanism to make the class smaller. Being strict on attendance seemed like the "least bad" of several rather unattractive alternatives.
I'm hoping that someone has a better idea, and I'm completely open. Please come and see me in 739 Soda.
And I have to say that it is already a huge problem at Berkeley to simply get enrolled into a CS class. There are simply not enough resources to go around. That's why this class has a huge waitlist.
By the way, this problem is also occurring in other classes, but they are scheduled as Monday-Wednesday classes. My class is Tuesday-Thursday -- the first day of classes at Berkeley was 8/29. Monday is Labor Day holiday at Berkeley, so those other classes will have to deal with their situations on 9/4. (However, their TA deficits are not quite as large as those that we have in CS 161).
