I found the sections on The Power Process, Surrogate Activities and Autonomy to be the closest to ERE (apart from the ecological and resource depletion concerns)
ERE and the method proposed in the manifesto both try to solve the same problems. FI goal falls in the (2)nd category and thus takes the person through the power process so that he can gain complete autonomy over his life.59. We divide human drives into three groups:
(1) those drives that can be satisfied with minimal effort;
(2) those that can be satisfied but only at the cost of serious effort;
(3) those that cannot be adequately satisfied no matter how much effort one makes.
The power process is the process of satisfying the drives of the second group.
The more drives there are in the third group, the more there is frustration, anger, eventually defeatism, depression, etc.
60. In modern industrial society natural human drives tend to be pushed into the first and third groups, and the second group tends to consist increasingly of artificially created drives.
The three drives can also be represented on an S-curve in reverse order on an input vs output graph.
Also he EREed since he retired after 2 years of teaching at Berkeley and then lived in a cabin he built himself on land he bought with his brother.
