>Greeks did it to their slaves
They also had sexual relations with freeborn boys.

>Because those societies were not able to prevent it from happening to any meaningful extent
But there have been plenty of sexually restrictive primitive societies which prevent both adults and children from engaging in sexual activities which they view as undesirable, including adult-child sexual activities. Arguably, tight-knit communities which were more common in the past were better able to police sexuality. A lot of people argue that we in the modern West are less capable of enforcing sexual morality.

Teenage women aren't less capable of giving birth and being mothers than older women are. Not historically, and not in the modern day. There has never been any proof that delaying marriage provides any sort of benefit to fertility. Women who have children at a younger age have more surviving descendants than women who delay child-rearing. Gregory Clark published a paper last year where he shows that the Western European marriage pattern identified by Hajnal was inversely correlated with fertility (and survived despite this due to some other factor):

Early marriage is only a hindrance if you consider women being whores throughout their 20s, marrying in their 30s, and having one child to be a good outcome (which feminists and Jews do).

The delay of marriage is one of the main reasons why we observe a catastrophic decline in birthrates among White populations.
