Risking being repetitive I disagree with your basic assumption as the web

This is where I don't agree with you. Yes, net-b certainly can't bill cust-a
(the web surfer) which is why it bills its own client cust-b (the web server).
Cust-b gladly pays because it has agreed to provide service to cust-a and
has calculated that whatever it pays to its service provider, net-b, will be
paid back by cust-a (perhaps site subscription fees or increased sales). So
net-b pays its settlement fees to net-a from cust-b's pockets.
Point is: the web surfer is only secodary cause to any traffic generated.
Primary cause is the web server providing content to be browsed. Web server
wants its content accessed and is willing to pay. (Funny thing is that the
web surfer is also willing to pay which is why Internet economics work and
it is heaven for marketing purposes.)
