I've read the whole thing. Frankly, this was quite a depressing. Something about this Economic Reductionistic way of thinking puts me off. Even tough I agree with a lot of his points — for example, the importance of communication over anything else — it just seems like a very one-sided worldview.
For example, he constantly outlines aspects 'business value', but not one sentence on the inherent, intrinsic joy of creating and building something (software in this case).
And I think you can't just ignore that part.
As someone in this post has put it quite beautifully:
