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.

I think that ignoring each other is probably the most common thing happening. One can look at wild animals sharing the same living space without fighting (or not, depending if they’re prey/predator to one another). Competition and fight happen when there is something disputed between them, bet it one serving as food to the other or some common resources. At least, as far as I understand it. It’s not that different for us, human animals ;)

I didn’t downvote you,

I did not designated anyone in particular, I was just trying to encourage whoever downvoted to also express their motivation/reasoning. I’m more than willing to learn from my mistakes, but I can’t learn shit without at the very least some form of an argument beside ‘Nah, don’t like u/what u said’ (which is perfectly fine by me, just not very… interesting).

Maybe some folks thought it was a cop out answer,

Thx, I did not know that expression and had to check its meaning. I can confirm it wasn’t a cop out, just the question that crossed my mind when I started reflecting on the OP question (a question I may have poorly understood, though, as English is not my first language).
