The matter of faked isn't simply INVALID, but rather when the

That is certainly a legitimate argument against challenge-response. What
you say does happen, but I believe it is very seldom.
As former victim of such a harvested email address being used
as sender for spam, I can only strongly affirm that the damage
is very real. I received about 2000-3000 "replies" on the first days
going from "user unknown" (usually from MS Exchange mailers) to real
insults directed to me personally (which must have been taken a
considerable amount of time of the writers too).
Even weeks after the event, I still received back scatter emails.
What I perceived as most damaging is that between all those "bounces"
(they do not all have the "Re:..." subject line either), there are
still some real normal messages for me, which I did not want to miss.
On the other hand, my procmailrc skills were making great progress.
