Ideally, you may have a path with ample bandwidth such that packet
losses don't occur and all connections are either application limited or
receive window limited and congestion control never kicks in. In this
case, there's no loss and the Internet clearly works.
This situation is not really "ideal" because it indicates an
unbalanced system -- you've probably spent too much on link bandwidth
and not enough on end system performance.
Many applications are inherently limited in max rate; e.g. VoIP and
video streams with fixed-rate codecs, telemetry, etc.
The elevator pitch should be that optimizing for low loss is harmful
and needs to be balanced with optimizing latency. It should not be
saying that loss is required.
