No, there are definitely physical and engineering issues, like massive rolling mountains and valleys, or island chains or deserts whose sand is unsuitable to durable railways.
Those are Edge Case. There will almost always be edge cases where we have engineering or physical constraints, but we have solutions for almost all individual trips.
You know that Switzerland, a country in the literal Alps, has one of the best train infrastructures on Earth?
As the other comment said, of course there are fringe cases. There shouldn’t even be a city in Dubai, let alone trains getting there, but fortunately, most cities on earth are in accessible places because, well, otherwise why would thousands upon thousands of people go there.

That’s a policy issue, not one of engineering or physical constraints.

Agreed, I updated my comment for clarity.
Definitely realistic, just not as profitable for rich billionaires.
