The bottom line is people like you want to puberty block children. You need to puberty block them because you need them to grow up and claim to be trans. You live vicariously through these children and the harms are inconsequential to you.
It's worth remembering why "trans children" were invented in the first place.
It's already been mentioned that the reason for the original Dutch experiment on children was because they hypothesised that the reason for poor mental health outcomes in adult male transsexuals was because they didn't "pass". They decided to create transsexuals who passed better as adults by selecting some children who would possibly grow up to be transsexuals, and prevent them going through puberty to see if they did pass better and if they had better mental health as a result.
There's also another reason for the creation of the idea of trans children. Since time immemorial, it's been known that men who indulge in crossdressing, and sometimes progress to transsexualism, are doing this for reasons of sexual gratification. These men want trans children to exist, since, as one of them (Autumn Sandeen) put it:
“I’ve always said there are two groups that are going to make change in transgender legislation and the “gender identity and expression” related language in legislation. It’s going to be trans youth because they take, you know, they demystify it and take the sex right out of the trans experience.”

These men see "trans children" as a sort of human shield. The implication is that because it's not a sexual thing for children, nor is it for these male adults. Which is obviously an outright lie, yet so many people seem to have fallen for it.
None of this is really about children. It's all about adult male transsexuals.
