By "your 'choice' " I was referring to the choosing you established in your phrase "that we chose to examine the system in . . . ." rather than a choosing ("choice") unrelated to the examination of the system.
There is no "choice" that exists unrelated to the examination of the system in that our particular "choice" of examination is what determines the outcome.
I would ask why, but I don't want to take us off track here. QM doesn't depend on free choice---choice being the supposed act of a conscious agent.
According to the founders of quantum mechanics (Bohr, Heisenberg, Wigner (!), etc.) and subscribers to the orthodox interpretation of quantum mechanics, it does. But, since I don't like this view and think is it wrong, I'll let it go (at least for now
).
You mean if everyone on earth died there would be no reality? Sorry but I don't buy your necessary reality.
Not at all. Simply that the reality that would exist would be radically different. If there were no "observers"/experimenters to interfere with quantum systems there wouldn't be any reason for the projection postulate to exist. That is, the entire reason for quantum collapse is written into the framework of the theory itself: how we CHOOSE to look determines the outcome. Normally, the effect of such choices is insignificant at best. However, the fact that "free choice" is an inescapable component of quantum theory makes any attempt to deal with causality, free will, consciousness, etc., necessarily a FAILED one unless it is able to explain how any reality emerges from our most successful theory ever when that theory REQUIRES we be able to freely choose.
Right, but in the collapse of the superposition, which will have a cause, there is no cause that determines its end state. Hence utter randomness. The cause of collapse and what it collapses to are two different things.
If I flip a fair coin, what causes it to be heads or tails and nothing else? My fair toss. The outcome is random (it is quintessentially random, in fact, and practically the default example). You have assumed a flawed, linear causal model in which outcomes have specific, unique causes (but have provided neither evidence nor logic for such a causal model). You have given no reason for electing from probabilistic to causally efficacious the role of chance (i.e., you assert that, given an inherently probabilistic system, what causes it to HAVE an outcome MUST be distinguished it from any PARTICULAR outcome, despite the fact that this would make it a system that isn't inherently probabilistic OR inherently random). What "causes" a system to collapse IS what causes it to assume the value it does or the state it does because THAT is what causes it to assume ANY state whatsoever. The fact that the transition is probabilistic rather than linear isn't a causal issue: CAUSING it to assume
a state is what causes it to assume the state it does out of those possible. Of course, if you argue that the probability distribution of possible states is somehow causally efficacious, than you must explain how the distribution of infinitely many functions (i.e., random variables) that has no physical existence whatsoever is somehow a causal force despite having no physical existence, instantiation, or reality.
So it would seem; however, the consequence of the superposition collapse says otherwise.
The consequence of collapse is simply that: collapse. It is the outcome of interaction of a particular type with a system that FORCES it into one of a number of possible states. If you assert that the function which determines WHICH of the possible states it assumes is the cause, than immaterial, non-physical, dualistic forces are clearly at play. You are rendering as causally efficacious that which is utterly beyond anything remotely related to the material/physical realm.
Because quantum physics is useful only because it is predictable, not "utterly random".
Because we've taken the subject of the OP off the topic long enough, consider my"why" here rhetorical. This will be my last word on QM randomness.

No, because "will" and "thought" don't carry the same kind of meaning as "free."
No. All thoughts have causes.
I wish I had read the red earlier. Fair enough: if it's your last word, I won't bother responding to the last parts and apologize for wasting my time and others' with those parts I have responded to!
