You have to understand that he is hiking, not focused on survival in an unplanned emergency. He is traveling through known territory and is very familiar with the terrain, conditions, and how both he and his gear function.
When I drive to the store it's a well travelled route through known territory where I know the terrain and conditions and yet I still carry tools and a spare tire. LOL
As a member of the ETS community and thinking as one who tends to study and talk about the topics we do, I don't agree with his conclusions. No big deal. If I saw him crumpled on the trail I'd offer him the use of my FAK and lend a hand. I'd probably be a jerk about it the whole time too. You know, ask him if he'd like me to drag him back to civilization in his sleeping bag greased by his deoderant to reduce the friction.
