Good article but in essence, it only works for freelancers, especially the 20 something kind who programs or designs and interacts with his customer through skype. Modern society has conventions that makes it work well. Like the expectation that the delivery guy will work from 9-to-5, instead of trying to deliver at 2am or in a Sunday morning, because that's optimal for his circadian rhytm. Same for the bank or the library or Starbucks open during the day. This convention lets us help plan our day. Without these you will have to plan for contingencies. These can be acute when you have a chronic disease, disabled or have babies/children. You just wish that everyone works 9 to 5 just so you can go through the day.
