Earlier quoted context omitted.
Correct... let me know what is if this isn't because companies colluding to set prices? not sure what I'm missing if this isn't it...
How is the answer misplaced? It's saying that you don't need price collusion or racketeering or mens rea of any sort to informally converge on a position.
It is saying that, but that's not a reply to the question.
The question wasn't "What is it?", as in, "What is this, if it's not collusion?"
The question was "What is?", as in, "What would it take to count as collusion, if this doesn't?"
"This isn't collusion, it's just the market" addresses the former question. It doesn't address the later question, the one that was asked.
With the implication that a super narrow definition of collusion is not very useful.
