“To some, opting out evokes images of gathering berries in a far-off wilderness. Liberation does seem to be easier in uninhabited areas – at least as a do-it-yourself thing, which it necessarily is for the first pioneers. But it is also possible in large cities. Imagine, for example, an old expensive building, which appears to be only a private club, but which conceals an entrance way to apartments and workshops tunneled underneath.”
