I'm sorry, but what part of the GDPR do you think demands invisibility? It doesn't even mention privacy because the GDPR stands of General Data PROTECTION Regulation.

the part where you are not allowed to profile the user based on a piece of information for which it is impossible to obtain consent (IP address).

The law does not mention privacy, correct, but its entire rationale is based on the idea of privacy rights.

The IP itself isn't much use in the context of personal identifiable information with more data say from the person's internet provider. Also, having http logs with IP addresses (stored for a reasonable short amount of time) is still allowed as it is a necessity to provide any service at all.

The regulation isn't about fucking IP addresses, it's about big data collection information about, what you buy, where you go, who you are friends with and doing shady things with that data.

> it's about big data collection information

This can be achieved with more sane, pragmatic regulation.
