If you fly the same plane regularly you're going to figure out in
short order what indicated speeds work for what weight. Make note
of them and adjust accordingly. When using 1.3Vso also keep
in mind how the speeds are listed in the POH. If calibrated airspeed
then you'll have to adjust to the correct indicated airspeed if needed
if you're calculating it from the book stall speed.

I think the instructor's reasoning is faulty. Why would the stall speed
increase as the airplane ages? If it has increased measurably, then
something needs to be repaired.

Bugs, dents, dirt would all change the shape of the wing. How much that
would
change the stall speed is an open question. Perhaps the FAA could be
useful
and do some research.

I don't even teach student pilots to fly faster than necessary. It is too
easy for a student to lose control on a fast approach, especially if he
balloons or bounces.
