I believe this doesn't disprove the need for storing in UTC.

I just think it means that you need a display filter that can specify
a timezone. It sounds like most of your times will be correct using
your system time, and if you have something that needs to be
displayed in a different timezone, specify it for that one entry.

After all there's no data lost in the plane example other than the
relative timezone of the observer. The duration is fixed, and the UTC
times are exact. Only the observer changes timezone.
