I may be reading too much into Mr. Suelo's thinking, but I think he has personally rejected money, not barter nor trade nor society in general. I don't think defining him as a hunter gatherer is an accurate or useful assumption. I think Mr. Suelo doesn't really care whether or not anyone else uses money. I think he views money, and its trappings, as society's primary control mechanism over him, and that he objects to that degree of control over him personally. He has noticed that in order for that control mechanism to work, he must first have money. And since he would have to voluntarily accept money in order to have someone else take it away from him, he has decided to non-violently avoid accepting money in order to minimize the degree to which he can be coerced. Then he has decided to use a combination of his social skills, vocational skills, and wilderness self-sufficiency skills in an experiment to challenge the idea that money is necessary to survive and interact in society. Obviously he is having some success, but I don't think there is much danger of his life style being adopted by the masses.
