I think the main concern is less about you (as a unique person) specifically, but more in terms of you as a somewhat aggregated profile. It's not super useful (also in terms of privacy and all that) to advertisers to get your name and exact home address, it's enough to know what "kind of advertising target profile" you represent most closely. I think that is also what many people concerned about privacy are missing — it's not about you, as an individual. It's about you, as a summarised profile, which can be shared with other advertisers. Being logged in or not used to be a bigger deal in the past, for sure, but now your browser and behavior is leaking enough detail to build a shared profile about you across various sites.
