While an IP address is not an identity, it can still zero in on a location. I suspect governments and ISPs all keep historical logs of who was assigned what address.
Do you have any source to back that up? Last I heard a random person or company won't have a way to find out the real identity given just an IP in general.
I am not sure how the CCPA treats IP address, but unless you're at Google or Facebook, it doesn't matter. Few can afford to build separately for the EU and the rest of the world, and hence err on adapting the strictest interpretation.

They do. It's often required by law.
I assume it could be easily challenged in court (network was compromised, “i give out my WiFi to anyone who visits my home”) without other supporting evidence.
To keep the discussion interesting, please do not assume or guess, thanks!
Anyway, it puts the persons living in that location on the radar of the police, and other evidence can be collected (For example by getting a warrant and taking all electronics out of the "location").
