The argument is that DMARC is a paradigm shift in email usage akin to the paradigm shift of "no-open-relays".

DMARC makes email so much more secure, as "no-open-relays" did.

The argument, if correct, means that DMARC is an unstoppable wave, because it is incredibly useful, so that the wise move would be to cooperate with DMARC, to be interoperable with DMARC.
Or perhaps are you, John, running an open SMTP relay? ;-)
