I don't know about you, but I am not married because of anything the civil authorities have done. I am married (26 years and counting) because I made a commitment to my wife and my God. I honor the state's right to make laws, but their laws have nothing whatsoever to do with whether I keep my commitment.
The problem here is that divorce laws (of whatever description) are like locks, they only work against those who don't need them. Anyone determined to evade either will generally succeed without too much trouble.
