Yep, it takes more time to shoot one sheet of film than it does to press the digital shutter. This isn’t the reason for using film: slowness.
That isn’t a good reason, since, of course, you don’t have to press the digital shutter often. you can control your finger, can’t you?

Controlling your impulse to push a button is no more a reason to use large film, than is becoming a prisoner of war a method of appetite control.
