I also spend about 30 min per day cooking for the kids. Would you say that I could "get back" these 30 minutes by hiring a personal cook? Well, maybe, but I really don't live like that. It's a mildly pleasurable activity, even if I'm able to imagine "better ways to spend my time".
Reread that comment. He’s saying you would have the option of doing that 40m bike ride, which you don’t have today. For the majority of people that commute will not be a nice ride through the woods, and they can’t opt out.
