Go 50 miles away from your nearest city and look at the sky. There’s a ton of places people live that aren’t light polluted to a level acceptable for amateur astronomy.
If the "nearest city" includes the edge of the suburbs, then perhaps. But there's a whole lot of sprawl in the US that has smeared the population across the landscape, with corresponding strip malls that have blazing lights 24/7.
I think the pictures that show the entire eastern seaboard as lit up may be misleading if one assumes they represent ground-level experience.
While I haven't been engaged in amateur astronomy for a long time, I vaguely remember an event/meeting years ago that was not that far out in the country, and just a few miles/minutes travel away from the "strip malls" made a huge difference. Northern lights were visible and I think the Milky Way.
I have been out west where it is really dark, so whether or not my recollection is accurate, I do know what undisputedly dark skies are like.
There are many places in the world where this is not a thing. I live in a densely populated country where it it simply not possible to get that far away from any city. If you drive 50km in any direction anywhere in the country, you would've encountered quite a few cities. I would have to cross several borders to get to a place without light pollution.
Netherlands? Germany (1 border) or France (2 borders) are fine. NL (I am from there but moved away a long time ago for this and other reasons) is more of an exception than a rule I would say.
There are a lot of hot spots on this map:

For the US, one-third of the population lives in coastal counties:

Two-thirds of the US population lives within 100mi (160km) of the border:
