Yet another whose lifestyle choice is viable ONLY because of the aggregate luxury of our society.
Kudos for achieving a happy (for him) life while remaining extremely frugal. I can appreciate & respect that (hey, see my tagline). It's a bit skewed, however, as much of what he enjoys is thanks to the overflow of abundance from those who create value; full-on capitalism is more fair as people are more aware of exchanging value for value.
Other than the fact that he lives on public land (not sure about the ultimate legalities of this...), what burden is he on society? Far less than the leeches at the occupy encampment (refugee camp). Or the hundreds of thousands of leeches living in public housing, receiving government checks, food stamps, etc. who are otherwise able-bodied.
He lives in a cave, but has a website? What kind of cave on publicly owned land has free electricity, unless he is breaking the law?
Wait? How does he get wireless in his cave? Who pays for his internet? Hobocast?
