That's not true! If Google has three ways and you eliminate one, and nothing else ever happens, then you might as well not do anything. But if there's one approach to data security that protects you from one kind of tracking, and you "set it and forget it," then it's chugging away in the background not really protecting you now—but if you later "set and forget" two other approaches to data security, then, together, they might have eliminated the problem, even if none of them individually made any difference.

(Stating the attempted refutation this way, it feels kind of like the privacy version of the refutation of "what good is half an eye?", e.g., https://evolution.berkeley.edu/evolution-101/the-big-issues/...)
