If you can positively identify the individual, you can say you don't want 
to accept mail from that person, regardless of where the account is.  If
the system I described were in place, you could decide to accept mail based
on criteria that the certifying authority places on those whose 
certificates it signed, and you would never have to know the individuals
or their ISPs ahead of time.  For example, you could say you only wanted
to accept mail from either people you specifically wanted (your white list),
or from any unknown people that were certified by having a notarized copy
of their driver's license (or whatever), which would then allow you to
specifically exclude particular people you didn't want to receive mail from.

In an ideal world we wouldn't have to worry about this, we could just all
be open and friendly and accept mail from whoever.  However, it is no longer
that way on the Internet and will never be again.  I agree that implementing
a scheme digitally signing mail is a vast undertaking that would never be
entirely complete.  However, I see no alternative in the long run.  Your
suggestion will always require a large amount of manual effort and you will
always be playing catchup with the spammers.  Using schemes such as Vixie's
blacklist is difficult for an ISP as it presupposes what individual customers
will want -- some of them certainly do not want to lose connectivity to a
portion of the Internet, even if it means exposing them to spam.  After all,
we can all certainly be free of spam by simply unplugging the wire, but the
cost is obviously too high.
