I'd say people who have an "enjoyable" commute is likely in the vanishing minority. And then they can simply reproduce their commute in their leisure time.
I have commuted on trains at various times and used my commute time in this way. Also, where I live in CA there are lots of people who bike to work (pre-COVID) and enjoy the forced exercise of their commute. Perhaps this is unique to warm-weather locations, where biking is easy for most of the year?
It was a good way for him to timebox the work, and stay consistent day-in-day-out without having to burn through a ton of self-discipline.
