having your life sorted doesn't mean doing the same thing with your life that others around you are doing.
not everyone should be a parent, even if they are biologically capable, that doesn't mean that they have the skills required (or the financial means, though this doesn't stop many people). if you look at all the worst criminals that exist, the vast majority come from parents who didn't want them or were otherwise incapable.
in the past, for example, many autistic women were forced into motherhood as they had no choice; and many were paired with abusive men or others who would not be able to find a partner in today's society. it is a big step forward, not backwards, that we now have other options... besides the obvious fact that there are already far too many people in the world.
