Teaching them initially to fly without a radio teaches them to look
outside and scan for traffic.
It's the fools with radios that think just because they broadcast over
the airwaves that they have the right of way and everyone should let
them play through.

The question was whether a student pilot should purchase a handheld
transceiver. If the aircraft does not have any radios, then a handheld
transceiver would be very useful to have. Although a radio is not
required in class E and uncontrolled airspaces, it certainly makes things
safer. However, a transceiver as a backup radio to the aircraft radio may
be an excessive measure. That was the point I was trying to make.
