Jazz story is just sad. If it weren't for his mom I doubt he would've ever have though of being born 'in the wrong body', Looking at Jazz's current way of life, it's hard to see any future that isn't him turning into a forgotten, lonely fat old man. Once his mother dies I doubt he would have any motivation at all to keep taking hormones, going to the doctor, trying to pass or take care of his health - he barely does take care of himself with his mom nagging him.
I do feel bad for such young kids being groomed/being directed straight to the 'you're trans, take hormones, surgery, and you'll be happy' when they are not 100% with themselves - which is actually normal, we ALL feel bad and weird when we are teenagers or even younger adults, feel bad about our appearances, or feel like we're trying to find ourselves, because well, we are - they don't have this opportunity to grow. It sucks, but everyone goes through this in life, and making the issue seem like it's one that will be fixed with medication and surgery seem genuinely easier to them. They are not dealing with life while they're busy pursuing their 'ideal/real body' and when they finally get it, they see they still have the same problems as before, just that they have waste their time and give themselves even more problems, namely health problems.
Again while I do feel bad for boys to loose all their sexual libido/unable to feel anything like Jazz, I always think of older males that transitioned after puberty. They're even worse, because i'm pretty sure 99% are just perverted, woman-hating men that dress as women to satiate whatever kink they have. They always hate women that talk back to them and don't support their delusion- just like other horrible, violent and misogynistic men of the their kind.
I also remember reading a few articles of detransitioners, mostly young women, that fell prey to the same type of grooming. Many of them regretting after a mastectomy or srs. But any detransitioner is fully ignored or ostracized and mocked. I've seen posts, including one that go 'I would rather 100 trans kids/teen to get hrt even if it meant one person regretting it'. The fact that a life would be ruined (and that number would be way higher than 1 in 100) and it's just a side effect it's already sickening. I've also seen posts being against Texas and (I think) Alabama law not supporting chemically castrating children that are not even old enough to have sex, making a tattoo or drink alcohol. Saying it's denying trans kids/teens healthcare - They aren't being denied healthcare, they are being correctly prevented of doing unnecessary hormone treatment.
