I don't disagree with what you're saying, I'm saying that these new rules intended to punish the parents for their decision also amount to punishing the child for the circumstances around their conception and birth, which I don't support.
But that isn’t true. Current babies have to follow the rules that already existed. If intended parents ignore these issues for future arrangements it is them that is punishing the child, not the state, by being willing to risk their child being stateless to get what they want. The simplest solution is to not proceed with surrogacy to avoid this situation.
And in any case, there will be ways around it. A gay couple would need to go to a country where one of them and the birth mother would be listed on the birth certificate as the parents, for example. After the child's birth they then enter into a custody agreement which states that the father has full custody of the child. The father then brings the child to Italy and says, "I had a relationship with [surrogate] in [country] and this is my child."
The Italian authorities can't do anything to stop that. But it could have unintended consequences. For example, if the father listed on the birth certificate dies, the child's next of kin is a woman they don't know who lives in another country. Or if the surrogate one day decides she wants her baby back, or even that she wants to live in Italy, she travels to Italy, obtains residency on the grounds that she is the parent of an Italian child living in Italy, and demands custody. These scenarios do not benefit the child. They are destabilising and create legal uncertainty.
Again, I am not sure what you’re arguing. This argument here is that the only way to prevent this is to not proceed with surrogacy! Which is what should happen! People should consider these potential outcomes before proceeding and not proceed.
But you seem to be saying that if Italians do proceed, against better advice and warnings of such outcomes, manage to circumvent the laws designed to prevent such negative outcomes then the best thing to do is just…let them off?
