I feel it more appropriate to say that the function of ground-mounted radials
is to harvest the radiation from a vertical antenna that splashes on the ground
and return it to the feed point for recycling.

The earth is a big resistor. Connecting to it BURNS transmitter power.
What many folks miss is that the function of radials is to SHIELD the
antenna's fields and return current from lossy earth, NOT to couple to
it. The only part of the earth we want to carry return current or see a
transmitting antenna's field is SEA water.
