I consider this kind of use of time machines logically impossible; it's a
classic grandfather paradox. In any case, such hypotheticals are
impossible to calibratable; there's no way to determine if stated
preferences mean anything and excellent reasons that past
preferences would be inaccurate and inconsistent. There's sound
evolutionary reasons for them to be meaningless side-effects of
the real use of preferences, guiding action.
