‘Sex is the one aspect of a person's identity that can never change, no matter how it is disguised.‘
I completely agree with you, I don’t think someone should be permitted to hide their sex at all. I would only agree to one piece of id not having sex on it, solely for the purpose of abiding by the Goodwin ruling.
Currently males are falsifying their documents, so when a male enters a female space and a woman complains to security, the man can produce falsified documents that say he is female (even though it is obvious to everyone he is male). While allowing people to remove their sex from a variety of documents may seem harmless, and could be in some circumstances, i.e. if it was only those who considered themselves trans that chose to remove it. The problem is that it will inevitably lead to the call for sex to be removed from everyone’s documents sooner or later, which would eventually lead to a similar situation we are in now, i.e. where we all know the person is male, but there are no documents proving it readily available. In other words I think it is a slippery slope. Trans lobby groups have already been pushing for sex to be removed from official documents.
Recently they have tried to get passports issued as ‘gender neutral’, but they didn’t succeed:
“During the hearing, Kate Gallafent QC, for Elan-Cane, argued that HM Passport Office policy breaches the right to respect for private life, and the right not to be discriminated against on the basis of gender or sex, under the European convention on human rights (ECHR).”
“Sir James Eadie QC, on behalf of the home secretary, submitted that the policy did not interfere with rights under the ECHR.
He argued that if the policy constituted an interference with article 8 – the right to respect for private life – it was justified by the need to “maintain an administratively coherent system for the recognition of gender”, to maintain security and to combat identity theft and fraud, and “to ensure security at national borders”.
“Mr Justice Jeremy Baker upheld Home Office policy after the court was told it would affect other legislation, cost too much to change computer records and increase the need for consular support abroad for gender-neutral British citizens.”

The appeal also failed:

I don’t see why similar arguments that won that case couldn’t be used to argue for the removal of the GRA itself e.g. if repealing the GRA interferes with article 8 – the right to respect for private life – it can be justified, because retaining it causes too much conflict with other legislation, the ideology behind it harms children, weakens safeguarding etc.
