The "original affluent society" theory is based on several false premises and is fundamentally outdated, but people keep it alive because it fits certain Rousseauean assumptions we have. I recommend reading this:

There are so many things wrong with those time estimates.
Well don't just accuse, insinuate and link. Lay out a few actual assertions.
I just read the 'original affluent society' and (most of) your linked essay, I kind of agree with you. That said, the conclusions of Kaplan lead to estimates or 35-60 hours a week (excluding some depending on the group) and that surprised me a lot. That's very different from the image I got from some other comments in this thread talking about extremely long days with constant back-breaking work. Would you agree?
