Sender verification is a necessary but insufficient tool in the anti-spam arsenal. It does little to nothing *BY ITSELF*, but it enables the use of tools such as Domain-based blackhole lists that are impossible without it.
Just because a hammer won't hold two boards together doesn't mean that it isn't a construction tool.
SPF IS an anti-spam technology, because it enables more effective anti-spam measures.
SPF IS NOT the solution to spam.
SPF right now is great fodder for your Bayesian filter, and blocks quite a few hostile e-mails cheap, such as from=recipient pattern spam/viruses. Nobody else in the world needs to use it for you to gain those benefits, since you can apply a weak "default" SPF record to any domain that doesn't publish.
