Could I accomplish this by using coax as the ground-wire and choking the
outer braid by sufficient windings on a toroid core, and grounding the
center conductor and the braid to earth though good and deep grounding
spikes or wires?

Offhand, I would say you could accomplish a DC ground
that way but not an RF ground and not much lightning
protection.

I suspect you to be correct; a "free ride" is just too much to hope for
in these times.

Well, even a dc/60hz ground which does not radiate rf can be useful.
