Do you have material needs and desires but weren't born with a priori knowledge of all possible goods and services that might satisfy those needs and desires?
Most newborns do not rely on commercial advertisements to learn how to satisfy their needs and desires.
We're not newborns our entire lives either, that logic doesn't work. Advertising is "natural", targeted AI curated reaction trash isn't though.
Okay, well I'm sorry you're too young to benefit from advertising, but your parents who change your diaper and everyone else old enough to be considered a consumer certainly do.
