Ironically, IP addresses are probably the _least_ personally identifiable bit of information in a lot of that stuff. Most people's IPs are assigned to someone else within months, or even hours. But a username, profile picture, etc? Those are potentially identifiable.

In a reply to your sibling I explain how in my view, the fact that lay people have no mental model of what kind of information can be incidentally collected and how dangerous it is, whereas lay people are much more capable of understanding the dangers of a personally identifiable username, profile pic, and personal details revealed in posts, makes the former far more dangerous than the latter.
