Unpopular opinion:

Wives are a form of human property by Nature, (as are all legal dependents). They're the highest form of property, tho, because they aren't transferrable and they have rights specific to their station, including the right to renounce their station.

Men are expected to protect them and provide for them because they are "his". They can't be his unless he can lay claim to them, in some way, through legal title or Natural Law.

The feminists are actually right about this and pretending otherwise just makes us sound illogical. It says it, right in the Bible:

“You shall not covet your neighbor's house; you shall not covet your neighbor's wife, or his male servant, or his female servant, or his ox, or his donkey, or anything that is your neighbor's.”

-- Exodus 20:17
