> Paying for a car and being defrauded is in no way related to being tracked by websites.

This is incorrect: they're both examples of informational asymmetry being used to disadvantage a consumer. In both cases, that consumer needs to possess technical knowledge in order to understand the ways that the counterparty entity is exploiting them. In the case of the car dealership, at least the consumer is aware of the stakes when they step onto the lot, i.e. they are planning to buy a car. The problem with Facebook is exactly that people aren't aware of how they are being monetized, and that there is an explicit financial incentive to obscure that from them. They are stepping onto a car lot, or more accurately a surveillance operation, that has been made to look like an amusement park. "Personal responsibility" is a convenient fig leaf for people who want to pretend that the amusement park wasn't the sales pitch. If you don't like the original analogy to a used car salesman, consider the need for similar regulation around financial services, clean water, pharmaceuticals, etc. etc. etc.
