My original idea for the fence was to use eyebolts and rivnuts to close the wire, similar to the drawing below:

So I'm thinking... is there such a thing as a stainless steel sleeve that can also be used to hold the wire so that it does not move?
That way I would eliminate the rivnuts, eyebolts, and the loops. And it would be just one piece of wire across several posts. Something like this.
In theory, it's one piece of wire that crosses all 3 posts, and this stainless steel sleeve would be holding the wire:
