I would focus on links that stand a chance of generating clicks. I would not pursue a link that will not bring any traffic.

That sounds quite a bit like 'overall traffic generation'. How do you think that helps with Google SEO specifically? IOW: Why do you think there's more of a benefit to optimization for Google from a link that will get a click than any link whether it gets clicked or not?
