What's Wrong with Marriage?!

I saw a little post with a review of some hypothetical situations in Berlin.

"In hypothetical 'Situation 2' a 22-year-old man has a 15-year-old girlfriend with whom he wishes to have sexual relations."

Solution : the 22 year old man and the 15 year old girl marry.

In some jurisdictions, this would require some extra consent for the 15 year old girl.

In Austria, under the Emperors, the 15 year old girl being already past her fourteenth birthday, and not being 21 yet had to ask her parents to marry the 22 year old man.

In Spain, today (or at least a few years ago), the fifteen year old girl, being past her fourteenth birthday, not yet 18, would need to write a letter to a judge who could give her dispensation.

"In 'Situation 6,' a girl named 'Milena' has an 'unwanted pregnancy.' While the document discusses options for receiving state support for her as an unwed mother, or for adopting ..."

And why would Milena not marry the father of the baby?

"In 'Situation 5,' readers are told, 'Laura (15) would like to sleep with her boyfriend and considers different contraceptives.'"

Why contraceptives instead of getting married to him?

There are even more shameful things, like child murder, on the agenda in the link where I got this from:

But situations, 2, 5, 6, all of them avoid discussing the obvious solution, which is marriage!
