I am curious what you base this statement on. As far as I am concerned 
anything that cuts down on threats helps. Would you consider port 
knocking as security through obscurity?.

Yes port knocking is more of the same.  It's not really the right direction to head for a measurable increase in 
security.  In fact port-knocking could potentially be found vulnerable to new attacks. As can devices that try to fake 
every port as being open.

Isn't all security when distilled just security through obscurity?

No.  Real security is a lot more scientific.  There is a great list of early publications on the subject here: 
http://csrc.nist.gov/publications/history/index.html.  If you haven't done so, have a read through the Orange Book 
(http://csrc.nist.gov/publications/history/dod85.pdf), and what security evaluation has become in the Common Criteria 

It is all about raising the bar.

Depends on your goals. That may not be sufficient for more sensitive environments.
