You are failing to make a distinction between the edges (access) and the
core (ISP's backbone and interconnects).

At the edges, where multiplexing is relatively low and queueing is
required, loss or ECN is necessary to regulate queue occupancy.

In the core, where traffic is highly aggregated and queues are generally
tiny, (excess) loss indicates insufficient capacity, and that some users
are suffering due to other people's traffic.   In the core losses (or
queueing) are nearly always a bad thing.

This one sentence is sufficient to solve much of the net neutrality problem.
