Even disregarding fingerprinting, a single household doesn't have enough traffic from separate devices/users to the same servers to really matter from a privacy standpoint.

If my PC uses the same IP as my partner's to talk to Google, it hardly matters for our privacy if they mix up the attribution of traffic between the two of us.

Speak for yourself. I also don't want it to be readily apparent how many different devices I have, or when I'm using which one, or how many people are in the household, or when who is home.

Granted any service that I consistently interact with is likely to be able to figure out at least some of that information if they put in some effort. But I don't want to be freely providing a complete picture for zero effort.

Creepy data aggregator stories pop up on the HN front page regularly so hopefully I don't need to explain why I feel this way.

Yeah, I mean, I share those concerns in general, but my efforts are mostly centered around aggressive ad/tracker-blocking (moderate DNS-level blocking at the network level, more aggressive at the device level + browser-level blocking) and the avoidance of non-privacy-focused services, e.g. avoiding the popular social networks entirely, and using privacy-supporting pay-for services.

Using the same IP for all of my devices, for me, generally falls into the same bucket of anti-fingerprinting techniques that are used by the Tor Browser like letterboxed resolution that I don't find practical for general use. If I want to actually prevent fingerprinting by IP, resolution, etc. then I'll actually use the Tor Browser.
