Bud forgets to mention how easy that problem is eliminated even by
protection inside panels. That thousands of volts is easily
diminished to near zero by a milliamp conductor - the neon glow lamp.
Bud has hyped a fear and ignored the solution that already makes the
problem irrelevant.
What field is far more destructive? If trying to earth a surge via
a plug-in protectors, then the safety ground wire inside Romex induces
surges on all adjacent wires. Fields from nearby strikes are easily
made irrelevant. Fields created by an earthing wire not separated
from all other wires can induce surges on those other wires. Only one
of us actually learned this stuff from both IEEE papers and
experience.
Meanwhile Martzloff describes in the very first conclusion of his
IEEE paper how a plug-in (point of connection) protector can
contribute to damage of adjacent electronics (as also demonstrated on
Page 42 Figure 8):

Bud likes to forget the parts that show how obscenely profitable plug-
in protectors can even contribute to electronics damage.
