It presents too many logistical problems. I need thousands of questions like that, I obviously can't generate them using an algorithm. Captcha can be generated automatically. I also need questions that are specific to my site. If everyone uses the same questions then they'll fall into the spammer's hands. Furthermore, there is the question of parsing the answer provided.
