> the answer is that nobody cares to.
This is an over-simplification of truly mind-boggling caliber.
If you correct every brain-dead thing people tell you on the internet, either never say anything remotely controversial so you don't get ill-informed but confident replies, you spend all day correcting people, or you literally just started saying things on the internet to tell me how to live my life.
But you responded anyway. You just didn't respond with anything useful. So what you did, essentially, was waste 10,000 people's time by having them look at your non-response "response".
countries routinely do things that are contrary to the interest of maximizing their net power, and claiming "but it's anarchy out there!" isn't very accurate.
If you need to pretend someone is arguing something they've never argued so you can disagree with them, you really need to take a step back and ask yourself what the fuck you're really doing.
