Your concern is far fetched because your assumptions are wrong.
Assuming about one of a thousand mail addresses in a spammer's address list
is a spam trap,
a spammer may be able to send one or two thousand spams (but certainly
not billions!) using his newly acquired domain before the domain gets
blacklisted.
would you care to describe to me why spf is at all necessary if spam
traps are this efficient? After all, blacklists have existed for quite a
while, and still, ever so many spams are circulated. If spam mails would
originate from spf-conforming "spam domains" run by the bad guys, what
advantage would spf buy in spam avoidance?
