What if the opponent's opening book leads you into the Evans Gambit?

Besides lots of hidden threats, a 20 move deep opening book might be half of the
game.  A 50% time advantage is the same thing as having a CPU that is twice as
fast.

You can get a small amount of randomness from an opening book.  This is
important to avoid getting nailed by the same problem over and over.  If I see
you have lost two games in a row by QGD, guess what I am going to play against
you.
