The way I read the article, the author has become totally bored and alienated with modern photography and in his search for pastures new has found a way to reconnect with an idealised past that never existed.
This is probably the same process that drives people away from Microsoft Word and toward Moleskines or fountain pens. Away from mp3s and toward turntables. Away from the supermarket and toward the allotment. Clearly this process won't work for us all and it's easy to pick holes in such things. But to me it seems like a much more personal project that's quite fuzzy but clearly makes some people happy. Convenience is all good, but maybe people need an outlet where effort and reward are better matched.
For the author he's probably equating extra time with extra effort and therefore greater reward. I feel the same way when I bake bread - it's far more rewarding than driving to the supermarket. My guess is writing with a fountain pen on nice paper is a much better experience than typing into Word. I think for most people there's something in their lives where they take a "more effort" route to get a greater reward, the slow food analogy fits here. For the author it's photography. We should probably encourage it - it'll help sales.
