I think the circumstances does make a difference-it’s not as black and white to me.
If I or any other offers to carry a baby for a relative/friend who can’t, then it’s a choice made with free will and a beautiful thing
As soon as there is any money involved, at whatever stage or whatever reason, then the free will and choice is muddied and it becomes more of a commodity issue.
I feel the same with abortion; I agree with it in cases of assault, where the child has complicated health issues or wouldn’t survive etc, but I don’t feel women should have multiple abortions if they get pregnant and it doesn’t fit in with their plans (I don’t know whether this actually does happen though).
A blanket ban on either is not required, but regulation and difficult conversations are needed
