IP addressing is intrinsically topological, so this is never going to change.
(Temporary IPv6 addresses are not long-lived, but they remain topological.)
Which is an argument for not using IP addresses end-to-end.
Which is exactly what is being done to conceal the IP addresses of peers in certain end-to-end messaging platforms.
Every communication infrastructure has to end up being topological at some level. Ergo, if it is desired to conceal location, at least one level of indirection is required.
I did spend some time working out a way to do this really effectively so that every communication session was protected from traffic analysis and even got some running code. Then I backed it all out as I was the only person likely to implement the result and ease of implementation takes priority at this stage.
