That is kind of the entire point of the article. This quote summarizes the argument which you paraphrased after pointing out "You have no idea what you are thinking". The argument to spell it out in a clearer way than the author is a reductio ad absurdum: 1) The system protects us from unsafe airline and car practices. 2) The system tries to ban toys and sodas. 3) Therefore, the system can protect us from anything that is bad. The conclusion is clearly false, because lots of bad things still happen and you can't engineer a perfectly safe system. The omnipotent entity he refers is the the government, market, or whatever entity makes decisions you don't have to. In the full article there are lots of examples, from banking to whatever where the train of thought jumps from one type of savior to another, without ever pinning it down on the individual.
