Must surrogates I know are in favour of this. Their greatest fear is people perceiving a link after birth where there is no longer a link.
If a pregnant woman cannot face up to the reality that if her body is creating the baby, it's her baby, and if she has to artificially create a severance of the link between a woman's body and her rights to the baby inside her to justify to herself what she's doing, she isn't mentally prepared for the reality of her situation.
If you have to contrive an artificial justification for what you do, you are deluding yourself about the exact nature of your choices.
A woman is free to create a baby, birth a baby, and she is free to sever her own rights to her baby. But every woman must be seen to sever her rights entirely free from coercion, and in the full knowledge that she has those inalienable rights in the first place.
But if she has to tell herself that sometimes babies inside women aren't even theirs anyway, but instead belong to someone else? If she has to tell herself that some pregnant women don't have any rights over their babies inside them in the first place? If she has to tell herself that to live with her own decision, then she's seeking to rewrite women's rights to their babies to sell to her own conscience that what she's doing to her child is of no consequence. She's seeking to build an artificial obligation upon women to sacrifice their own babies by contriving that some women don't have, and shouldn't have sacrosanct rights over their children.
To donate blood or organs, a donor doesn't have to lie to themselves that they don't really own them and have an obligation to give them away. To donate, you have to give informed consent and have full capacity to give it. You can't sign away your rights months ahead and watch a recipient override you if you no longer consent.
Consent is something that can always be revoked.
