I didn't downvote you, I think you offered a thoughtful critique of the question.
Even if parties have wildly different objectives or winning conditions, if they didn't have to compete for the same resources then they could cooperate or at least ignore each other. That wouldn't be true if it were a race to finish first, but in that case they've started competing for the resource of time.
Maybe some folks thought it was a cop out answer, since I was seeking new perspectives rather than a reason to not ask for them? But, I think your response can help guide responses to even more extreme examples than some potentially topical ones by taking you up on your challenge.
But those are just different debuffs!
