My point is that in the eyes of the state, your sacramental marriage will be irrelevant. To Christians, what’s actually irrelevant (or should be) is state approval or state sanctioning. So, the hell with the state. I don’t need them to recognize my SACRAMENTAL marriage. My wife and I will sign whatever papers we need that will make ourselves each others heir, give one another durable power of attorney, next of kin status, etc.
Good Lord man, do what you want, you don’t have to have a legal marriage, you didn’t in 1780, or 1880, or 1980, or today.
If you don’t care if your marriage is legal, then don’t go through the process to make it so.
Nobody forces people to do that.
