Population of Switzerland is around 9 million people. Slightly larger than NYC.
Comparing a country with the population of a single city in America is disingenuous. There are probably some cities in America that have faster internet than Switzerland.
I'll briefly reiterate the essay's primary point, for your convenience, which is agnostic to population size: when a natural monopoly exists, the best solution – regardless of ideology – is to make the underlying infrastructure at once singular and public while fostering competition at the level of servicing that infrastructure. That is how Switzerland accomplished its highly functional fiber-optic network, a system that is at once cheaper, more reliable, and more performant than its US and German peers.
This is a perfect example of my earlier comment: you are talking around the subject, cynically dismissing the point of the essay without even addressing it.
