I don't think you have understood the article. Try reading it again without bias. Your comment seems to be a rationalization of your own job. The author is positing that there are situations out there where you could love your 8 hours a day of work and the time after it. And that in most cases you can do this by refocusing on your minimal "needs" as opposed to the many "wants" that you feel due to a variety of pressures in life: "nice car", "big bank account", societal, status-symbols etc. Also his post is aimed at technology professionals who love technology but just need to find the right situation. So it's much less riskier than changing fields but people still don't make the effort to find a better situation. And I've seen the very same thing happen.
