I guess the idea is to provide some shields to people making a transition, as they could suffer ostrisation or threats from people who have animosity against transgender.

Not everyone is a world famous artist that certainly can hire a whole team of body guard h24 all year around if they feel like it's appropriate.

I'm not aware of the the law in question. It seems strange to me to target specifically naming the person with this or that name, rather than cover the case in a more generic way like creating threats on someone's life or social integrity through public release of intimate information.

Deadnaming is typically done to be a cunt, which is a whole lot different than published works not having your new name on it.

Yours is not a remotely apt comparison of the situations.
