Of course, even Spamhaus's own website says the PBL is not a blacklist
and that you can remove your IP address from their list if you are
running a "legitimate" mail server, but only if it's a static Ip
address. They provide no definition (that I can find) of what
constitutes a "legitimate" mail server

Most ISPs I have seen charge considerably more for a static IP
address; generally, commercial prices rather than home-user or
small-business prices. Unless you have relatively high bandwidth
requirements there is no point. It is *definitely* not worth the
expense just just to avoid an occasional over-zealous mailserver admin
spuriously binning one of your perfectly valid email messages. Even if
you are hosting a website or an incoming mail server, there are plenty
of dynamic DNS services available for many times less cost than having
a static IP address.

A large percentage of spam originates from the USA. It would be just
as rational to block mail from all IP addresses that are listed as
being there. (-;
