According to you. Where do rights come from? Are they just what ever things the state has decided to grant, or are they a claim that our moral status as humans entitles us to be granted certain guarantees by the state. When Thomas Paine wrote The Rights of Man, could the whole thing have been dismissed on the grounds that the state hadn't actually granted these rights? It's like conflating the natural right to free speech, with the 1st amendment. This is a natural rights claim. Normally we talk about what natural rights people have as if we were, in the manner of John Smith, discerning the angelic writing in which these rights are transcribed. I don't see people saying, well in the 18th century giving full rights to black people would have caused all sorts of logistical challenges and maybe done more harm than good, so back then they didn't have the same natural rights as white people, but now they do. Natural Rights are imagined as being timeless, universal and independent of implementation difficulties. Claims to natural rights are the ultimate moral underpinnings of most modern liberation movements aren't they?
Again, do implementation difficulties now count against other claims to natural rights? If we are thinking of the past, that seems like it would have been a very easy rebuttal to lots of liberation movements.
Maybe I misunderstand you? If so, could you clarify?
I don't know where theprestige lives, but in the UK, the actual wording of the Equality Act of 2010 recognises sex-segregated spaces, especially those for women, as a right - they are exempted from other provisions in the EA regarding discrimination. By extension, those who are not legally considered women (at this time, Gender Recognition Certificates turned a few thousand men into women, legally, as a fiction) are not entitled to enter, i.e. they have no right to enter.
So the right is codified in British law, but this has been violated by an expansive interpretation of the Equality Act of 2010 put about by Stonewall when advising institutions on how to best implement equality and diversity. Self-ID crept in long before it was being considered as a matter of law.
In Ireland, and presumably Canada, where self-ID is law, then the statutes likely spell out what rights are held by whom.
US statute books clearly vary with some states imposing self-ID and others denying transgender people the right of access to bathrooms of the opposite sex

The majority of US states don't have such explicit legislation, although federal administrative ordinances regarding Title IX would hold sway in higher education (and those ordinances changed from Obama to Trump to Biden). The Wiki article is a good primer on these matters, from the perspective of legal rights.
So when a Brit in this thread says that transwomen have no right to enter women's toilets (without a GRC), they are speaking the truth regarding how the 2010 Equality Act is in fact worded; the loosening of interpretation might be explicitly tightened up under Sunak, or so it's been hinted to the Telegraph this weekend.
Irish and Canadian women have no substantive right to eject transwomen from their bathrooms etc because the laws there changed, although Canadian women can at least refuse to wax Jonathan Yaniv's testicles.
There's no need to confuse the matter with natural rights as if this is a history of political ideas course and we're discussing Bodin, Hobbes, Locke, Smith or Paine.
There are actual laws, and actual political debates and arguments which change those laws, reflecting contemporary understandings of different groups' rights. These laws are subject to change, and groups will feel differently about 'their rights' after the laws have changed, but also because of how the laws are or aren't enforced. That way lies the genuine sense of injustice from different sides, which no amount of citing statute books, or dead philosophers, can actually quell.
