There you go again David -- hyperbole...
"If we had Cannara's world, where the entire network was owned by a
benevolent government monopoly (or one owned by a small number of
corporations who are free to collude, but never conduct network wars to
screw each other up), perhaps we could apply traditional control theory..."
Others can certainly get your idea that your ideas are The Ones, but that's
not the point here, now is it? I know you know the point, and I'd be happy to
pop over to your office to discuss it. The point is stagnation in network
design, which started long ago in the Internet clan, and is now maintained by
lack of dedication to good engineering. I notice you avoid responding to all
the various examples of why dedication and responsibility are so important to
well-engineered products. Did you have some trauma induced by a cold call
from an AT&T network center? :]
