Interesting thought (which I know was partly in jest). Let me comment...
The emphasis on *weight* among the lightweight backpacking community often misses the point -- having a light pack isn't in itself necessarily beneficial. Instead, the award is what you can *do* with a light pack, though what you can do isn't perfectly correlated with pack weight either. The weight issue is also a cause for concern among newbies and old-schoolers, who equate "going light" with being unprepared and/or flimsy gear.
So instead of writing a "lightweight backpacking book," I wrote a book about the backpacking gear, supplies and skills that are necessary to love *hiking*, while still staying safe and comfortable while *camping.* I'm not proposing an alternative approach to backpacking. I'm telling you, "If you want to enjoy hiking, read this book. If you want to hate hiking, read a NOLS book or (too often) Backpacker magazine."
To help make this point, I created a fictitious character, the "Ultimate Hiker" which is a backpacker (like me) who optimizes their entire system for putting one foot in front of the other. They assess the environmental and route conditions they will encounter on a trip so that they can be adequately (and not over-) prepared. They have good backcountry skills, so they can supplement what they don't carry on their back with what they carry between their ears. They know how to use gear correctly, so they don't have to take foolproof items that are oftentimes very heavy (e.g. double-wall tent compared to a tarp). And so on.
The book is written for backpackers who want to *at least sometimes* be *more like* an Ultimate Hiker. Really, it's written for beginners and intermediates who are stuck being "Campers-by-Default," who I define as backpackers who do not have the know-how to actually enjoy hiking. Unless they are willing to suffer, these hikers simply prefer to spend most of their day camping, because walking is intolerably miserable.
