John Galt Has Been Located
It seems that he turns out to be a Hmong tribesman, living somewhere in Upland Southeast Asia. From a review by Tyler Cowen:
The subtitle is An Anarchist History of Upland Southeast Asia and the author is James C. Scott of Yale University. Here is a summary from the Preface:...I argue that the [Southeast Asian] hill peoples are best understood as runaway, fugitive, maroon communities who have, over the course of two millennia, been fleeing the oppressions of state-making projects in the valleys -- slavery, conscription taxes, corvée labor, epidemics, and warfare. Most of the areas in which they reside may be aptly called shatter zones or zones of refuge.
I believe that this says most of what I always wanted to say about civilization and its libertarian discontents.
