I suspect you shouting CANNOT is probably overstating the issue.  After all
if offset was of no value how would NTP (or any other offset based time
transfer system) work?
To the previous point -- if someone says "my offsets are always 10s of
microseconds" that is likely to be a refutation of the 'NTP can't do better
than 10s of milliseconds" position.

I don't know what "terribly accurate" might be to you but in the real world
sufficient accuracy depends on the circumstance.

Someone should conduct an experiment.
