I think you would be very interested in the rest of the document. That is very similar to the point that the author makes throughout. He suggests that spending more time on fulfilling our primitive needs of food water and shelter would result in a much more satisfying lifestyle and much higher quality of life.
Sure but it's a degenerate ideology. We can all base our lives on what feels good or what's satisfying but primitive lifestyles aren't going to save man from a dying planet. Kazynski was a degenerate, if you use TFA's definition, so trapped into his own local mindset he couldn't see the wrongs when in context of the global.
