I haven’t looked into the history enough to conclusively say this but it seems that marriage is inherently statist. It has all the qualities of control you’d expect from extortionists. Women became the property of her husband and took on his last name. Her father would get some type of payment. What other reason did anyone have for writing a marriage contract before? Taxes? It seems like it was just for record keeping. Whether it’s government, a monarch, or the church. It all seems to serve the same purpose.
