: >>>Perhaps some people would go of their own free will. I imagine many forts being built along the Greenway and along the East-West road, and perhaps towns would spring up around them. For example, people coming north to farm, or to set up inns along the road, people setting up shops along the roads and profiting from the increased travel of Dwarves, hobbits, and men, etc. People could probably make quite a decent living by moving to Arnor, but at least that is how I imagine it.

Yeah, I guess they could.
When I look at my map here, I imagine Bree as an important trading post because of its location and because it was already inhabited. So people would not have to start all over again.
