No, I think your just missing his point, whether deliberately or not...

The point was that althoug the traffic flows would appear balanced, they would
be artificially balanced by wasteful automatons asking for or delivering
traffic with no benefit just for the sake of consuming bandwidth in the opposite
direction in order to balance assymetry.

There's a difference.  Power is inherently a one-way flow, and whichever way
it is flowing obviously has a TO is purchasing from FROM value system built
in.  This is not inherently true in IP traffic, and so the model doesn't work
as well.

It's not fraud if you create real traffic.  It's only fraud if you claim
traffic that didn't exist.  Reread the legal definition of fraud.
