How do you figure? Why is refrigeration and freezing a necessary part of this diet?
I suspect part of your thought process is built around the tendency of the modern, industrial people who adopt raw paleo diet to view themselves as individuals, and to build isolated, individual lives for themselves. As individuals, one person can't eat a whole deer by themselves before it rots, so freezing or refrigeration is necessary. Also, your particular diet relies heavily on industrial fishing, which also requires refrigeration and freezing to be viable because of the quantities of fish involved.
In a tribal culture, rather than every-person-for-themselves the participants would work and eat as a unit. If one hunter in a tribe of 40 people killed a deer, it would be divided among everyone in the community and folks would eat nothing but deer for a few days until it was all gone. Even in warm weather deer meat won't go bad for a few days, so in a tribal culture there would be no need for refrigeration. Same with fishing. If a fisher brought in a substantial catch that he couldn't finish by himself, everyone in the tribe would eat nothing but fish until it was all gone, and refrigeration wouldn't be needed.
And tribal fishing and hunting is also done on a smaller scale. So the hunter would never bring back 10 deer all at once because that's too much for his tribe to eat in a reasonable time, and the fisher would never bring back 10 tons of fish all at once, he'd stop fishing when he caught enough to feed people for a couple days.
This ignores the potential for storing some of this meat by fermentation, or salt curing. But that's another issue...
So I guess I disagree with you GC. I think we could do this without refrigerators or freezers, but our culture would need to change for that to be possible. We'd have to be willing to work together as tribes, and when meat is made available we'd have to be willing to share until it's gone.
