Whether there is a PUBLIC announcement or a private commitment is irrelevant.Marriage, a public announcement, is a proclamation to the community of commitment, one to the other, and their progeny of care and responsibility.
As for tribal arrangements or different kinds of marriages, study some history. The so-called sacramental marriages did not exist before the church declared them. And they are not superior to any other kind of mutually accepted and reinforced arrangement. Of course they are not inferior either… they simply do not matter.
