I agree, this is kind of dumb. I mean, he's right about the technology trap, but he keeps talking about "you" and "need a plow". If it's just YOU, why do you need a plow? You do not need to raise huge monocultural fields, and if it's a farm, it will be easy to work with what has been plowed before.
I understand what he is getting at, but it just seems as if he is a city dweller who thinks heading back to the land is an insurmountable effort. It is difficult, but far from insurmountable. And odds are, any decent farm will have manual versions of just about every saw, drill, etc, since it is frequently easier to head out with a hand auger or saw for one hole or cut instead of fighting with generators, etc.
But if it inspired you, good. I can see how this would cause one to think, but it seems driven by fatalism.
