For one thing, I hate my handwriting. That's probably a main reason I got so deeply into computer technology in the first place. For another thing, during my first cup of coffee my greatest urgency is getting out of the house early. If I don't give my employer the best and earliest hours of my day, I will end up dozing off at my desk around noon. I cannot afford to be caught with my eyes closed and slack-jawed.
Once I become retired, voluntarily or involuntarily, I will happily institute morning pages, because I believe in Cameron's rationale for them. But even then, I will be pressing keys, not pushing pens.
