Why give it path into your house?
I agree, but there's a better way of looking at this. Lighting is an RF
event, not a DC event. Most of the energy in lightning is between 100
kHz and 10 MHz, so the shield of the coax running between the tower and
the shack looks like a big inductor to lightning. If we bond to a good
low resistance, low inductance earth connection at the base of the
tower, lightning will go there, not to the shack. The radials can help
by providing capacitive coupling to earth.
