Surrogacy allows science to fix injustice
Some parents can not have children naturally. Science, through surrogacy, can fix this injustice.
They is no permission needed to have babies naturally and some people who have children are unprepared to parent or do not want their children at all. On the other hand, people who use surrogates are undertaking an expensive and arduous process in order to have a child.
The surrogacy process insures that parents have a real desire and motivation for a child. Many children are born to families in which they are not really wanted, but babies born to surrogates are clearly wanted and therefore are born into a more welcoming environment. Correspondingly, parents who use surrogates have been found to adapt to parenting more comfortably than children born to parents naturally.
Surrogacy does not guarantee that those who utilise it will be good parents - it is entirely possible that people will go through the process and still fail their children. Many people do not use surrogates for medical reasons, but instead because they do not want to take time off work or carry a child. Additionally, the debate around surrogacy should be concerned primarily with the wellbeing of the surrogate, rather than the child.
[P1] Children born to parents who use surrogates are guaranteed to have been wanted due to the arduous process prospective parents have to go through. [P2] Therefore, surrogacy brings about children that are more likely to have a high level of wellbeing.
[Rejecting P1] Surrogacy does not guarantee that users will be good parents.
