> even if you escape the sedentary village, the stable neighbouring village will happily return you to "your owner" so that he would hopefully return the favor if ever he catches one of "their slaves")

Tell that to all the people who ran the Underground Railroad in the pre-Civil War US, not to mention all the other ways that Fugitive Slave laws were persistently violated.

I think you are vastly underestimating the benefits of a modern "sedentary" society. But as I pointed out in my other post, if you really don't think they're benefits, then you can simply forgo them. Go and live an off grid subsistence lifestyle. There are people who do that. But of course they don't post on the Internet.
