I don't think he said it doesn't work, let alone that he's no longer doing it. I also feel like a 4 day work-week for employees and a 4-day work-week for freelancers ought to be pretty different. You're going to have to find clients, do paperwork, and other unpaid managerial duties as a freelancer regardless of how long your work week. If it's 5 days, guess what? That stuff is eating into your weekends and nights.
