It's fairly defeatist that the misery couldn't be solved or that most people would find life to be miserable. My example specified "everyone else around me," so the anti-natalist has to make this incredulous argument that not only was I extremely lucky, but almost everyone around me was lucky as well. They would most likely fall back on "uh acktually, they're not happy, they're just being polite, you don't know what they're actuallly thinking."

Like I said earlier, anti-natalists have to sooner or later resort to denying the subjectivity of other people. Because overall, most people don't feel all that bad about their life. Even in places that are facing literal genocide like Gaza, I see Gazans holding on to the hope that Palestine will be liberated and Gazans getting on their knees to prostrate and thank Allah even in the midst of utter misery. Not to make light of their situation, but it's honestly very inspiring that they can see, hear, feel, smell, and taste so much death and destruction but yet still have the mental and emotional resolve to march forth and face another day, day after day until the day of liberation when they can feel the soil and breathe the air of a liberated Palestine. Anti-natalists can call it cope or religious brainwashing all they want, but it's quite clear that for all the misery that comes from genocide, they don't actually hate their lives but instead hate the wretched entity with all their hearts, the source of their misery. But instead of a vague notion like "existence," the Zionist entity has a history. It has a beginning and a middle, and it will have an end too. It was made with human hands, and it will be undone with human hands as well. This is why anti-natalism is rightfully associated with depression and reactionary defeatism because that's what it is in the end.

Consent, when applied to an agent that doesn't even exist yet, makes no sense whatsoever.
