According to the interview he only has an internet connection two or three times a day at most. In that sort of scenario his set up kind of makes sense. If I only had short bursts of internet connections during the day I'd probably also set up a system where I could queue up URLs to be automatically downloaded for offline reading next time I had a connection.
You're missing the point. why does he have such limited connectivity?
Actually there have been at least a couple of threads about working without internet on a some of the RV/nomad threads here, and based on those I'm considering trying pulling the plug on my internet connection for 4 hours at a time when working to see what it will do be my ability to focus on the task at hand and not get distracted by hacker news. Perhaps Stallman has a similar approach.
