You're the unusual case here: the vast majority of folks in the US end up living within a stone's throw of wherever they were born. And you'd be crazy to deny that there are many legitimate reasons to do so: Deep local social networks and family ties? Long-term investments in housing or other local property? Rearing children in a stable environment? Niche subject-matter experience and expertise in a trade that isn't necessarily as portable as digital skills are? Belonging to a particular local subculture that doesn't necessarily exist elsewhere?
