I’m not sure how is it particularly different from medieval Europe in that way? But there are other reasons why traveling and moving to different regions was relatively rare for most people (e.g. almost everyone was extremely reliant on their local social networks, so moving to a different community was very costly). Of course metalworkers and other highly skilled craftsmen were probably always one of the most mobile groups (in pre-Roman times and during the middle ages as well)
