(1) You are wrong, at since the middle ages in Europe. See child comment on Western pattern of marriage. I would be interested in your sources besides Romeo and Juliet, where if I remember correctly, they are told they are too young.
(2) The referenced article isn't really about marriage, but about the transition from adolescence to adulthood. There is a difference between a person getting married/ starting to have children versus setting up a household in which a person has an "adult" role; in the recent, Euro-derived West they are one and the same, but not so universally. And in the West, late age for marriage, and lots of non-married is the norm, and that pattern is pretty unique in the world.
If you do a graduate degree in demography, you learn all this. There isn't really any debate about it anymore, though it is very cool and interesting to discuss because it challenges our received knowledge about "normal". Don't get me started on fertility rates for women over 40 and their historical trends....
Among poor people in the US it is fairly common for a girl to have her first baby when she is 17 / 18/ 19 but still live at home; she has hardly left adolescence even if the boyfriend/ husband is also around...
