Often, it has actually been the case that the bad guys just did X, which
was obviously possible beforehand.  We went to great expense for nothing.  
Why didn't anyone think about what the bad guys could do?  [we tend to
characterize such obviously failing schemes as hair-brained, (or perhaps
"hare-brained" for the rabbit-watchers), but this is probably unfair in
some respects. An honest and direct answer is appropriate.]

You can't fight spam on the assumption that abusers can't change. But
nearly every anti-spam proposal does just that.  That is, if it has any
rationale about how it will affect spam or anyone at all.  Anyone who
suggests that the abuser can simply do X is generally not well received.  
For example The email authentication scheme promoters don't even consider
reactions or ill-effects. They just take it as given that spam will be
prevented if we have authentication.  But even perfect authentication
would have no effect on spam. [skip the details, assume users are
perfectly authenticated, then ask "so what?"] A very expensive
authentication system doesn't even require much change to what spammers do
now.  Yet the "best technical minds of the IETF" don't agree with this. Or
rather, just ignore the "so what?" part.  That isn't engineering, that's
just amateurish experimentation at our expense, and perhaps their profit.

Of course, if you take that analysis of channel usage to its logical end,
one will find that you can't prevent spam. Or more specifically, can't
secure a communication channel against topically inappropriate messages.
