There is a certain degree of hypocrisy lingering: "I want to know where everything comes from and be in control and yadda yadda", but then you're using yellow plastic gloves probably made in China by some pollution-heavy factory, dishwashers, plastic chairs and sheep-shavers made by people doing those jobs you so despise, and going back to Russia every day in something that is unlikely to be a wind-powered boat... And how is the wind-power guy "off-grid", when his website was an early internet hit and he (like the violin maker) probably derives an income from the "outer world" thanks to his activities?

Living in a society is always a compromise, these people have just struck a slightly different subset of trade-offs -- but to sustain their lifestyle, they are still largely dependent on the wider world being what it is.
