I don't comprehend what's so hard about making public bathrooms accessible for everyone. in Australia disabled bathrooms are common and anyone can use them. Single stall unisex toilets are becoming more and more common too. my high school had a unisex toilet block with full-height stall doors (no gaps). This is not that hard. It's only difficult for other english speaking and European nations to get their heads around because of some old building code mandating male and female bathrooms (in the US) or the UK requiring a license to open a disabled bathroom or some shit. It is not hard. It is not a challenge. Single stall unisex, disabled bathrooms for everone if that's not possible, and if the venue genuinely only has male and female, just don't ask questions. GAHH
