It really is a pain that since we live in different parts of the world your posts arrive when I'm at work, when I can't give them the attention they warrant. I will say your post is heavy on assertion and short on actual evidence, though. For example I don't know why a long time without farming strikes you as impossible or absurd. Why shouldn't it be so long? There are severe costs to farming, primarily the need to stay in one location [i.e. where the farm is] and that restricts your feeding opportunities from other sources [eg migrating animals] dramatically. Farming only becomes viable and cost-effective when the benefits outweight the disadvantages.   In fact we know of an example in very recent times [a vague memory puts it at 11c, but that might be wildly out, and isn't too crucial; I will look it up if you want]. A modern-style farming community set up on the cost of Iceland and pretty much sneered at the 'primitive' nomadic indiginous people. Come a series of hard winters, the farms were ruined, and all the incomers died whereas the nomadic people coped without any problems at all. Farming is not a wonderful thing in itself - it is a solution to a particular problem.
