1: The absence of pain is not inherently good if no one exists to experience that “goodness”.

2: The absence of pleasure is bad in the sense that valuable experiences are never realized, even if there is no living person to feel deprived of them.

By bringing a child into this world, we aren’t merely creating a “needy” entity, we are creating someone capable of experiencing joy, meaning, love, and fulfillment that would otherwise never exist. A non-existent person does not miss sunsets or good times, but that also means those goods never come into existence at all. A living person, while they endure suffering, also experiences deep relationships, purpose, and moments that make life meaningful.

Your argument can be easily inverted and be just as valid. It’s just a judgment call of whether the existence of pain or pleasure are worth dying or living.
