How, then, is the electric vector from the electromagnetic wave going to put these electrons in motion?


That's what I was referring to. Do you understand why he would pose
this question


As already stated:
But from experience we know that /no/ electrons can
ever be caused to move without gradually establishing their own magnetic
field, and this usually takes /time/.

The need for time (impedance) is accommodated by the wave:
It can only do so because the electromagnetic wave
/also supplies a magnetic vector/ as well as an electric vector.


The phase of the re-radiated signal is a function of the path length.
If the path signal required the electric potential to sustain movement
(no other motive force available), that would add an additional phase
retardation that is not observed.

Observation of what does occur is other wise described by Bailey as
from experience we know....


Roy's quote comes from a nascent discussion of the topic of Reception
that has a complete, later chapter devoted to it.
