Yes and no. The more time passed, the more people there came to be. Which led to competition for territorial resources and boundaries. (And what seems to have been recreational as well as all-out warfare). This is a process first evident back as far as the Dalton era and continued. With the Benton Archaic you start seeing materials traveling over the span of a hundred miles or so, then continental movement of selective, high-status lithics with the Mound Builders.
Most of your points are Archaic, and from later than the early phase when trade in pretty/high-quality lithics (Dovetails for example) was a thing of the past. Maybe your local history was an exception to the general rule.
FWIW.
