You said yourself that it was a method to control overpopulation so it is probably just temporary solution, because in that rate population will turn to zero in no time. I expect government was using advertising and other propaganda methods to convince people into believing that death is not bad at all because they wanted to save on healthcare and safety.
so I labeled it brainwashing just like current government is brainwashing everyone into crazy consumerism.

About that castration, you are giving too much meaning to that, because my idea was that it happens just as form of playing without any thinking about consequences.
but this is not actually good thing so parents should scold kids for this.
if you do this in clinical setting it is no longer casual but very bureaucratic. and this ocficcial setting signing waivers waiting in line dealing with sadistic doctor is quite a turn off for me.
the reason of castration shoud be something very comical like boy gets scolded for displaying his penis in public and he decided that it is nuisance.
In case of playing doctor they are just curious to see what is inside his ballsack. so it is not completely voluntary, but lightly coercive in form "I will show you mine you will show me your's"

if you treat that as favor it implies that it was somewhat bad to have balls so it is no longer so casual.

another idea is that kids while playing stuff something important in the girls vagina and then must use knife to take it out.
