Right, I knew they were separate things. I meant only that widespread adoption of Bitcoin would obsolesce both; should have phrased that more clearly.

  it is simply a metric that private parties have chosen to 
  reference when setting. Libor is influenced by central 
  banks' rates, but so would a Bitcoin economy's reference 
  rate be a function of international money rates.

Yes. My point was that not all private parties would "choose to reference" things like LIBOR, nor be forced to participate in the Fed's quantitative easing schemes by virtue of holding US dollars. That is, with a distributed currency like Bitcoin (or perhaps a descendant of Bitcoin with even greater anonymity), we pull back a lot of control from what is currently a hypercentralized, opaque system.
