I think your article has some valid points. But I think time available is not the only thing in the equation, as a few other commenters have pointed out. For example, I also work remotely, but I've found myself suffering from burnout lately because of hectic schedules. This has been a mentally draining experience, and as a result I've not been able to even begin thinking about side projects, let alone work on them. I do have more time available to myself than when I used to work in an office, but the time available to me now is worth way less than when I was working in an office because of my current job's intensity.
