Well, let's broaden our thinking a bit. Maybe you wouldn't make $1,000 US dollars a year but you might be able to barter and obtain the equivalent annually. This is just one possible answer but my point is that he made a broad, general statement that's not a detailed blueprint for every possible situation. I make statements like that about the small amount of crops I grow and sell. I tell some people you could make $1,000 per year selling snow peas, and I have in the past on a property I owned in PA. That doesn't mean that every single American hobby farmer can do exactly the same in every single situation. There are many variables such as weather, equipment you own, land available, commodity prices, etc., etc., but the statement remains true. You can make $1,000 a year growing and selling snow peas on 1 acre which many of the yards were back where I came from. Some will do better and some will do worse, but it's just a general statement about what could be done if certain conditions are met. That's the way I read that statement. Of course it doesn't apply to some poor soul living in the Sahara where there's no vegetation, water, or people around for 1,000 miles, but it does apply to many people living in the average conditions for the area. I could easily pick apart every statement he made by pointing out a theoretical case where it wouldn't work, but heck you could do that with just about every statement ever written since the beginning of time. If everyone thought that way nothing would ever get done.
