An inherited "behavioral" habit is certainly based on historical fact and therefore difficult to change, even though some people consider tradition to be fiction, or merely a fabrication of the beliefs of past generations and then carried out as an obligatory mandate.

The tradition of early marriage is not driven by poverty or a means of protection (survival), but rather as a group identity that is accepted and believed to be a social truth and a "guideline for life" for a group. This is because tradition is one of the oldest behaviors in the world, meaning it existed before the country's economy collapsed, even before the nation was formed.

If a tradition is related to religious values, then religion predates the concept of a sovereign state, and most traditions that have developed to this day are behaviors inherited from past kingdoms. I think this is the main reason why changing the norm is so difficult, because it is historical fact, not fiction.

Yes, on the one hand, early marriage is very ironic, and our common sense rejects the continuation of this norm due to the cruelty to adolescents' rights and freedoms, the risk to their lives, and the gender gap. In Indonesia and several other countries, this norm also exists, and it continues to this day.
