Fair enough, I agree that we could be here all day if we opened the value-judgement can of worms (though I do wish we did this when discussing public economic policy).
Economists generally claim this outcome to be "unrealistic" but it helps us understand the more traditional outcome
I agree with this. Just to add, pretty much every simplified market model you would find in an undergraduate-level textbook won't correspond to any market in reality. As you suggest, they're just very simplified models designed to 'kinda point you in the right direction', rather than be taken as a description of reality. The most dangerous people tend to be those who took micro 101 but were never told the latter :)
