I don't think he ever meant it that way. It's not that he "cannot take a leisurely walk without distraction", but that he wants to get some walking while working, i.e. the priority is reversed. He claims to walk for "a couple of hours" which is too long to not be doing anything for him. You seem to be generalizing a lot from this one person's preference. Also, a lot of people listen to podcasts/audiobooks while walking/jogging. Is that a "distraction"? I'd say it's actually even a plus and those two activities are complementary to each other: Being in the wild helps you concentrate on the audiobook, and being able to read something uninterrupted motivates you to go out and do some exercise every day.
