Accounts of unicorns in antiquity had rather different horns.
That is certainly recent enough for their memory to persist in myths.
As you say, the narwhal tooth is indeed the source used for most medieval illustrations of unicorns, but not the source of the legends about them.
Even just goats seem useful here to explain the often depicted medieval unicorns beards compared to earlier sources.
I wonder if the perspective in the article comes more from a Protestant understanding of Mary?
In Catholic teaching at least, Mary's "fiat" ("Yes") was one of the most pivotal moments in salvation history, and Mary is regarded as the "Queen" of all saints, for her role and her personal decision to say yes.
A couple of paragraphs on a profound subject and reductionists feel the need to talk over it as if they have a better idea.
If this stuff interests you, get out of the shallow end of the pool.

There's no map, just fields of doors. You get nowhere by arguing about the look of the doorknobs.
One thing is for certain: there are no unicorns in Silicon Valley, no matter how much it has loved to profess as much.
