Looking at the links, none of them suggest that surgeries are performed on children. Puberty blockers aren't surgery. Intersex children are surgically mutilated without their consent but adult trans people need an OK from two psychiatrists. If I had had puberty blockers (reversible) as a child, I wouldn't have had to go through something painful. I was only able to start hormones at the age of 23 when all the changes had already happened. Hormones aren't able to reverse everything. Then people complain that we don't look good enough when we were never given the chance (unless you're rich enough to be able to afford surgeries, which I'm not).
