The point is that a) it’s unfair to expect individual consumers to make a difference and b) it’s not realistic to expect individual consumers to make a difference because network effects are so powerful. The modern world exists in part because of cheap, plentiful oil. If you live most places in the US, you need a car, and probably a gas-powered one at that. Similarly, Facebook gobbles up information about you even if you decide not to use it. You can’t stop using Facebook even if you aren’t using Facebook, because Facebook is actually using you and the billions of other people it siphons data from. This libertarian wet dream of “just don’t use it” doesn’t work on a large scale.
