That underscores my point that the purpose of the marriage (so far as the state is concerned) isn't procreation then, because the state didn't do it. Didn't try to do it until fairly late in the game. Pile that onto my earlier note that we allow the infertile, aged, and simply unwilling to marry and that no marriage license asks for anyone's ability to procreate or even intent to do so and so far as I'm aware never did.
The state didn't abandon it. It didn't have it for most of our history.
Here are some states that made the attempt by law or change to their constitutions to mandate the gender:
Arkansas (2004, 1997), Georgia (2004, 1996), Kentucky (2004, 1998), Louisiana (2004, 1999), Michigan (2004, 1996), Mississippi (2004, 1997), Missouri (2004, 1996), Nebraska (2000), North Dakota (2004, 1997), Ohio (2004, 2004), South Dakota (2006, 1996), Tennessee (2006, 1996), Texas (2005, 1997)
