Now, using your analogy, what if 9 of the customers aren't even using their system, say it is after hours and they've shut down. But the 1 remaining user tries to do a data transfer using the full bandwidth of the system. Under the Comcast method, that user would still be "packet prioritized" and his EFFECTIVE SPEED for that transfer would be attenuated.
That doesn't happen. The node is not saturated.
This is The Key Point you seem to want to ignore.
