The family name goes first in East Asian names, reflecting the fact that they value family over individual; Whatever the parents' idea of "family" is, triumphs over the children's individuality.

I use such name and this is pretty much the dumbest take on our names.

This seems a shallow take to me, couldn't you just as well go:

In the US people adress eachother by (Mr/Mrs) family name, putting the family above individuality.

Which ofc is less prominent in the US than in more communal cultures like those in Japan or China.

Right, all Eastern countries are the same in this, as are all Western ones. Family was never know important than individual in any Western country for as long as family names have existed.

Legit, there's no child abuse in US.

I can't vouch for all East Asian countries, but in Japan, it's a matter of formality. When you meet someone, you always refer to them by their family name and an honorific. (Like we would say, "Mr. Smith.")

Once you start to get more friendly and familiar with an individual, you'll move on to more intimate honorifics, until you're allowed to call them by their direct first name, no honorifics. That's a sign that you're very close with someone.

It allows people to refer to you without being too direct and familiar until you've gotten to know them well. And you can tell what relationship two people have by what names they use to call each other. Heck, really close friends will probably make up nicknames for each other too.

When I was in the US military, it was kind of the same mentality. Everyone was referred to by rank and last name only. As you got to know someone of the same rank or lower than yours, you could refer to them by last name alone, no rank required. But only the closest of friends would refer to each other by first name.
