I don't know how you found that post confusing. It's pretty clear: a fixed-length work-week for any type of creative, rewarding or challenging job isn't ideal. (I added the creative, rewarding and challenging part, because I'm sure it's implied).

The op's point is that the freedom you think we ought to enjoy, isn't freedom...it's a rigid pre-defined template. Real freedom, when it comes to work-life balance, is working the amount of hours in a week which you want and is appropriate.
