That’s a legitimate question and here is my thought. What you call “wage slavery” others would call productive labor. In this modern world, labor is so highly specialized it’s sometimes hard to see value in one’s work. You have to look at the big picture.
Anton is not living a self-sufficient life out in the wilds. He lives in an apartment in Boulder. He eats and shops and gets medical care and enjoys all the benefits that come from other people doing what you would call slave labor. His local Whole Foods didn’t come into existence magically. It’s a corporation. Real estate developers, bankers, construction firms, architects, city planners, etc built it. The Whole Foods corporation operates it. Countless companies supplied their products, which are shipped by transport corporations on roads that are maintained and built by other corporations contracted out by govt entities. It goes on and on, obviously.
The point is that Anton, living this kind of “selfish” lifestyle, is not really contributing to the system as others are. Hes not adding logs to the community woodpile, so to speak. There is nothing terribly wrong with this. He’s a law abiding citizen, etc. but to the point above, I’m guessing it leaves one unfulfilled on some deeper level as you age. (This is to say nothing of being a parent and providing for your kids as your parents provided for you.)
I also have a soft spot for these folks (ski bums, surfers, Anton, etc) as that lifestyle seems extremely appealing in so many ways. I wonder how I would feel myself if I took that path in life.
