I actually feel that humanity has had the potential to make a world or will one day actually realize a world where the innate experience of practically all humans is to have ignorable amounts of suffering. Like so little suffering that the word 'suffer' would become foreign to most humans' vocabularies.

And I feel that in a world like that? It would be perfectly OK for each person to have as many children as they see fit. I doubt that this opinion makes me antinatalist. Does it?

Sadly, Humanity isnt even anywhere close to that and we havent gotten close to that ever. Which is why I would strongly recommend against anyone ever producing a child seeing as how the innate experience for most is to suffer a sad , individualistic life plagued with dystopian monotony and unequal exchange.
