I highly doubt he ever said anything of the sort.

As long as you turn a blind eye to what he states
then you are in good shape! But then somebody in this group
will point you to Tom's statement and you can then respond as
to what he really meant which is not what he stated.




apparently
a break off from the standard ham statements of bigger is better as
well as more wire is better.



And the physical reality that antenna performance is directly related
to size in wavelengths.

It depends on your definition of "size". I prefer the term
encapsulating volume.
All physics laws are based on the presence of equilibrium. Thus you
may deform a radiator to the smallest volume as long as you retain a
state of equilibrium, regardless of the number of wavelengths at
issue. This is why "point radiation" is still discussed.
As an aside, the number of wavelengths used has nothing to do with
Maxwells equations
which accounts for ALL forces presence in the forming of radiation and
not the simple
radiator coupling and re radiation approach alone. It all comes down
to root L.C. in a equilibrium environment as the determinate factor
in his equations.

So, the bottom line is that you disagree with the statement made by
Tom as being incorrect.
It will be interesting what the rest of the group have to say as they
wade in.
