Barter evolving into cash in this particular case would be fine -- the
general idea is to increase the cost per email to the point where spam is no
longer economically viable. Since response rates are on the order of
0.0001%, this shouldn't involve a significant increase in cost.

Could be. One of the advantages of the proof of work scheme is that it is
much less fungible than real cash, and as a result, much less interesting to
people wishing to defraud the system. It's my understanding that fraud is
still a big problem for the likes of PayPal.
