No. You cannot answer a single 1-person question to two peoples at
once. I agree with that remark.

Of course.

Yes, but I ask the question *before* the duplication. So I do ask the
1-person question to a single person, about its *future* experience.
 The comp ignorance is that that
person cannot be sure if he/she will feel being in front of ZERO or ONE
in his/her next future. Before the duplication you1 = you2, if you want.
Before the duplication you are in a state of maximal ignorance about
your personal future. Of course after the duplication, just looking
at the wall and seeing ZERO (or ONE) give you one bit of information
making it possible to distinguish yourself from your double.
The indeterminism is really a prediction-indeterminism. It is not
a form of identity-indeterminateness.
The indeterminism comes from the fact that
  1) You can 3-duplicate a 3-person (with comp).
  2) you cannot 3-duplicate a 1-person, that is, from the point of view
of the person, that person feels like staying one and unique, in front
of ZERO *or* in front of ONE.
