I disagree this is the ideal. The first implementation of PageRank makes a very big assumption: that people who write webpages and control websites can be trusted to link to worthwhile content. If webmasters and web producers skew a certain way, then PageRank/BackRub will also skew that way.
Google original mission statement was "to organize the world's information and make it universally accessible and useful." Being a mirror of web content would only partially solve that mission, and that's assuming webmasters/producers are acting in good faith. Would it really be ideal for Google to be a "mirror" of link counts for "miserable failure" [0] and "Did the Holocaust Happen?" [1]
