Btw, how critical is the resistance of wire in a few ground radials? I have
some thin stainless steel wire that would be strong and enduring out there
but at around 1.5 ohms or more per 6 inches I can't help thinking that's too
much. I like the idea though, because clamping ends of it very firmly between
copper washers could be fast and easy for good and reliable contact.

The stainless steel is a non-starter. Use more radials of wire-wrap
wire if you are concerned about visibility vs. thickness.
Vegetation/grass will quickly bury most wire when Spring comes (and
possibly before). Grass will be so tenacious that even mowing the
lawn will not bring it up (unless you have a thatching attachment).
