It's interesting to see the "I can do everything all by myself" approach vs. the communitarian/cooperative "you help me-I'll help you" Amish-style approach. Seems...empowering and lonely at the same time? I wonder what it is that draws some folks so powerfully to these kinds of solitary pursuits.
I guess personality is a factor. I am very much a solitary worker, myself (just not as skilled as this guy). DH can work alone pretty well, too, especially if there is no time-pressure. In general, however, his style is more social and communitarian - whereas I go out of my way to avoid involving other ppl.
I can see the benefit (assuming like-minded, cooperative ppl) in working together as a community. Still, it really goes against the grain of my personality to have to rely on others.
So I can see the appeal, really - but also the risks.
