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.
