If we take into account that the average person types less than 80 WPM (and that’s being generous) using a pecking technique and by looking at the keyboard, I can definitely understand how the average person would prefer writing over typing. After all, the same complaints that you have about writing apply to their typing technique. They think more about typing and which key to press, rather than the content.
Per another comment, this study enforced single-finger hunt-and-peck (and they specified which hand, you couldn't even use your dominant one if it was the other hand).
