I didn't read their post as an argument against WFH, just that they happened to like their routine. I happened to bike to work, about 10mi per day. I rarely get on my bike now, sure I could, but I liked the routine and it really helped me get exercise. Like the OP I'm not saying everyone should do that, just that it worked for me. If I had to commute 2hr in traffic by car I would absolutely prefer WFH.
