   Ergo, at least one of the three cannot be in your set of observables
for your states. By definition.

  I don't care if you disagree. Go look it up in any introductory quantum
mechanics book as I suggested. One of the reasons I have no interest in
continuing with this thread is that you bastardize terminology to suit
your agenda.
