I guess I missed that in the diatribe.

I understand that you see this as nothing.  We disagree on this point.  Not 
being effective against a man-in-the-middle attack is not equivalent to doing 
nothing.  Lots of security measures can be defeated by such attacks.  We still 
make use of such techniques and layer them with others to shore up those 
deficiencies.

The false assumption is that a technique that doesn't solve all problems does 
nothing.
