I don't necessarily disagree with many of your arguments, but I wonder
why — if everyone owns their own DNS domain — we even need the user@
portion anymore? Largely that was included because in the early days —
and even today, for many people — their addresses were
theirname at theirprovider.domain.
My primary personal email address (not the one I use for mailing lists)
is pretty redundant since the part before the @ is the same as the part
after the @ once the parent domain has been excluded. Leaving off the
user@ portion doesn't make the address any less "mine".

Calling a Jabber ID an email address is a bit misleading. It's entirely
possible for the email address user at example.com and the JID
user at example.com to be owned/controlled by different people. It is not
safe to assume that the two are the same person without evidence of
that. What makes a string like "user at example.com" an email address is
the fact that you can address email to it. The fact that the two
addressing schemes use similar syntax doesn't help you much.
