The benefit is pretty obvious. If my IP address and identity information

send email to an individual unless I am willing to reveal that information to
that individual. And I can't send email through any server operated by anyone

These may not feel like important issues to you, but for some people they are
life-or-death issues, and there really is a tradeoff to be made between the
freedom of people in that situation to speak, and the freedom of the operators
of mail servers to surveil them, even when that surveillance has a good motive
behind it.
Is email the right system to use in that scenario then? If your IP
address can locate you to that level of detail to anyone who looks
(which is NOT the case for the vast majority of people), then you're
probably in the situation where you can, and should, work out something
better.
If your IP address can't locate you that precisely, but only to your ISP
(which IS the case for most people), so that someone has to contact your
ISP to find out exactly where you are, then they can contact your ISP to
find out from their obfuscated-IP (or email address) who you are anyway,
so it won't help there.
