Should the age of consent be raised to 20?

[Boobs]

If no one would have sex outside of marriage, this wouldn't be an issue.

Yes. If no one drove cars traffic accidents wouldn’t be an issue, and if no one consumed any fuel or electricity or products manufactured with them climate wouldn’t be an issue. However, based on context this thread seems to be focusing on the real world, where none of this will ever be relevant.

And it’s not even accurate? People could get married at age 18, to someone older than 20, and this hypothetical age of consent would still matter.
