The post you're replying to is suggesting that removal from Google results _should_ be part of US law. Perhaps the impact of Google is such that there should be legislation regulating Google's behaviour.
In the UK we have a public phone book maintained by British Telecom. I can opt out of the phone book but BT cannot choose not to include me if I've opted IN. BT is a private company but this one aspect of their output is regulated by law.
The difference between a private company selling a service and something considered an essential utility is legislation, presumably?
As if this excuses any kind of behavior.
Specifically, in this case there are in many countries antitrust laws, which target public and private companies alike.
If our system worked, Google would almost certainly broken up and most of their databases (full of people's private information) couldn't exist legally.

Their results can influence a great number of people, it can make or break a business, and it can (probably) cause or at least greatly contribute to a revolution in some countries.
You know, hence why countries like China want to control such power.
Google indexing fairly is every bit as essential to the maintaining equal opportunity for websites and businesses on the internet as net neutrality is.
If you can make an argument to the contrary that doesn't revolve around "it's not 1776!" I'd love to hear it, but I seriously doubt that it would be in line with any US law. I don't think there's anything "stone age" about not requiring private companies to do things to help other private companies without compensation.
