I think those would all come under the disclaimer of ‘subjective opinion of author’. Or ‘subjective batshit opinion of author’.
Which I think helps rather than hinders the official PRH position, because there’s no actual snakeoil here, and it’s not simply a replicable cure.
Even Moth can’t keep up his own Salt Path miracle regime for more than two stints of a couple of months, even if we accept the timeline of TSP (which we may not). SW isn’t telling us to buy her essential oils/cook her whole food recipes/ have coffee enemas etc, because they work — Moth simply appears to be unable to replicate ‘homelessness on the path’ however much he tries off the path.
We’re told he tries long hikes carrying a pack, going to the gym, exercise bikes during the time at Polly’s, but none of it works.
Again in TWS, ‘Raynor’ thinks the problem is he’s been too sedentary while studying, and that he needs an stress-free, wild, green life. But when he gets one, on the cider farm, that doesn’t work, either, so they have to go and walk in Iceland.
In LL, he’s so weak, despite this green outdoor life on the cider farm, that he can’t even walk two miles. So obviously Raynor drags him off to walk the Cape Wrath trail.
This ‘miracle cure’ doesn’t work, or it’s only the most fleeting of amelioration, and available only to those who have the strength, leisure, money, skills, equipment, appropriate partner etc to take off and do LD trail walking. And if you can, are you going to spend the rest of your life doing so?
