Richard Posner Chief Justice?

I am probably navigating rough waters with this comment, especially being new to this country and to judicial issues, but certanly this comment by PrawfsBlawg does an interesting analysis of why Richard Posner would make a good case for a Supreme Court Chief Justice. Being my inclinations on the libertarian side I admire a lot of Posner and Becker's blog and I often hear them being quoted in free market - Libertarian -Conservative lectures. Would not be great to have a Supreme Court Justice like him? Thanks for the pointer to Instapundit
