Switching fingers keeps the tension from building up in the hand. If it's fast, it's a lot easier to switch fingers than strain using one finger.
However, I did speak to a pianist who used 222222 for the introduction to Scarbo, and she managed to do it remarkably well.
Thanks for your replies,I thought I was playing incorrectly when I heard recordings of the piece. I can't seem to play those repeated notes any faster with my single-finger technique. I will try to switch my fingers, but i just keep hitting wrong notes and it messes up my flow.Just curious is there any biological reasons that the switch fingering is faster?

As for thumb hitting wrong notes, my only explanation is that you are moving your hand too much, minimal movement. Hope that helps.
