Hmmm, a site with fluctuating traffic from Google vs. a site with no traffic from Google. Some... zero... Kind of a no brainer.
Even if Google was sending me zero traffic today, I certainly wouldn't burn any bridges by blocking them. Tomorrow may be a different story.
That said, it would be an interesting experiment to see how much you could build up a site without any traffic from Google.
