That's a different sort of trap, as it ignores the effects of circumstance (even minor things, like whether organ donation is an opt-in or opt-out checkbox can have huge real-world effects).

It also leads to blaming the unfortunate for making poor choices when those choices have been both constrained and biased by circumstance.

I strongly disagree with that and I believe this kind of thinking is not actually as logical or as rational as you were lead to believe, and properly asking the why question and answering it is fairly critical to figuring out what should be done.

> go with the flow

Go with whose flow? You realize that this is just you piggybacking on someone else's answer to the "why" and blindly accepting it without any kind of verification? This should be alarming, not calming.

Really, if someone somewhere was able to answer this question well enough that they could create a "flow" for you to go with, you can do the same.
