Then you need to get privy with a bit more information really.
In the States where adoptive parents are present in the room when the mother gives birth, where they take the baby immediately, some of those children still present with trauma and attachment needs, some of whom can suffer severely. Those stories are easy to find if you follow attachment and trauma studies, and the programmes and approaches families are involved in.
It's rather like transitioning isn't it? Because it works out ok on the roulette board for some kids, why worry about the ones it damages and has a lifelong impact on?
It is people trafficking, with all of the many issues involved, and that's before you look at the profound selfishness of commissioning a child with the open intent of depriving it of its mother at birth. The child is a commodity in this; it's feelings aren't considered relevant compared to the adult's desire to parent it. Pre adoption training for adults starts with the explanation that adoption is rooted in loss for all concerned; at least it is honest about this.
