That doesn't seem to be excessive? I find it a pretty short list of names that are just quite highly visible. It's mostly enterprises that provide some form of public good (infrastructure).

It's not an exhaustive list. At that, IMHO, it's too general to say these firms (sampled) produce public goods (i.e. nonrivalrous and nonexcludable). For example, I don't get the benefits from intermodal shipping via Hapag-Lloyd without paying.
