I think the thrust of the complaint is that the society doesn't sufficiently value privacy for its own sake.

In a different kind of society, websites of the sort that you describe would be unpopular, because users at large would place less value on the real-person guarantee than on the non-collection of their identifying information.

Closely related to this is the topic of end-to-end encryption. To withstand attacks that I expect will continue to be mounted on it, I think the society has to believe in privacy as a terminal good. The answer to the argument that "we could catch such and such criminals if we had key escrow" ought to be "yes, and not catching those criminals is a price we agree to pay, because privacy is just that valuable to us".
