Legality was literally the last thing on my mind, but I get why people are stressed about the socio-economic consequences. 200y+ of statist propaganda have tainted a lot of minds.

I was referring to the kind of special bond created between a man and a woman in a world where you're free to do whatever you want. I think it's amazing some people still choose to go old fashion.

Don't get me wrong, it's better to be in a loving partnership than in a loveless marriage. Personally I've found that agape is reachable rather inside the marriage than outside.
