Well, what you say is true to some extent, but there are some privacy extensions... And I don't think you should rely on having an obfuscated/shared IP for anonymity. There are better tools for this, like Tor, I2P, Freenet, etc. IPv6 was designed back in the 90s, where we had much less concerns about tracking, privacy and anonymity. But IPv4 is even more ancient, and, make no mistake, CGNAT is not designed to make you more anonymous, so you could be fooled by a false sense of security. Maybe we need to sell IPv6 as a way to track users to boost its adoption? And develop those privacy-conscious networks on top of it? Regardless, IPv4 and NAT are not consumer-friendly when it comes to self-hosting and p2p, so as long as these are the norm, software silos will be at an advantage.
