I can't stay in a long thread, but some quick thoughts.

You generally can't have galvanic action unless something is 
attached to the anchor that forms a circuit. INSULATE the anchor 
from anything else, and by all means do not use it for a ground!

Zinc, as far as I recall, is only attacked by acids. If I was unsure of 
my soil, I'd lime the soil around the anchor at install and the ground 
right around it every few years.

With normal soils, even if the anchor has no coating, rust will 
greatly slow down deterioration. The soil will hold the rust against 
the anchor, and somewhat protect it. I can't imagine rotting an 
anchor through unless the soil is very acidic or the anchor is 
electrically connected to something that is acting like a wrong 
polarity source.
