Self sufficiency to an extreme without having to be, seems just that, extreme. I agree though, that being able survive this way, if one had to, is an admirable trait.

"seems just that, extreme. "

IMO, its a relative matter. For those of us living in cities or suburbia it does seem extreme. I did'nt pay attention to location in the article, is this guy living in a metropolitan area?, if so, yes that would be extreme.

For those living in isolated areas of the Western U.S., Canda or Alaska, its more a way of life...extreme to the city bound masses.
