As for not being able to enter certain countries: i don't reliably pass as either binary gender now so either of those would give me quite a bit of hassle in those countries. For example, i don't think i would be particularly safe trying to enter the US with any gender marker. i haven't tried going to/through any arabic countries or Singapore; i heard (from an Australian) they tend to be very annoying about gender markers, even binary ones, but let (rich white) foreigners through after the hassle. And to be honest, being able to go "i can't come because they will 100% imprison me" tends to discourage your colleagues from scheduling meetings in places i didn't want to go anyway due to hatecrimes.
i travel a lot and booking things (plane, Eurostar, hostels with one-gender dormitories) is consistently broken even within Europe. i tend to need to call customer service half of the time. (Often they say: flip a coin to pick a random gender and call us to have it corrected.) Being handed an official goverment paper form and getting to draw in my own checkbox for gender feels like a victory though. For this, you do need to be a bit perverted about bureaucracy and the ability to use a phone call to make it someone else's problem.
In all, the X makes my life a bit harder, but it's a manageable challenge. Having the right name makes my life a lot easier. And the happiness from a correct passport matters too.
