Sure. Tell that to the people you work for who depend on e-mail.  When I
was a sysadmin (quite recently), I'd have gotten fired for enforcing
such an arbitrary policy.  Indeed when mail wasn't coming through that
someone in the organization was expecting and wanting, regardless of
SPF, it was indeed *my* problem and my job was on the line.  BOFH
attitudes simply aren't going to change that reality.

SPF is just one more of the many things that are contributing overall to
absolutely breaking and demise of SMTP.  I'm afraid when it does finally
cease to work, it's going to be replaced with less open,
centrally-controlled messaging systems like facebook.  Which is unfortunate.
