Ask HN: Digital nomad without leaving the US, why does it feel overlooked?

I am curious about digital nomading in the future and almost always they're traveling internationally, but I am more interested in hearing of digital nomad experiences that involve traveling within the US. There's still plenty of room to stretch your legs in a country of this size. Lots of beautiful locations that I'd like to visit and sight-see without me needing a passport.

Digital nomads somehow became more synonymous with air travel across the globe but for some reason I don't hear much about the ones who are backpacking and road traveling without leaving the US. Is it mostly because of the appeal to live more cheaply in many other countries?
