Drowning Nor Waving

Yeah, that scenario does seem to be based on having a lot of power capacity and resources. Maybe they're assuming more technological advances which will help? I tend to be pretty skeptical of technological solutions to collapse-of-industrial-civilization scenarios. It does seem plausible to me that some communities might have it together enough to at least send useful information and models to other communities--but I think there's also a danger, especially if the people doing so really think of themselves as missionaries, of that being done with a narrow-minded, self-righteous attitude that their approach is better, when the "farm communities" might have more knowledge of the local ecology, geology, history, etc., as well as more experience in practical survival skills. What works best in one bioregion isn't necessarily a good strategy in a different one.
