But is that really an issue though?
I'm guessing almost certainly that most people are going to react to these later issues the same way people reacted to gay marriage. "Oh noes, my rights!"
I honestly can't see any benefits of arbitrary restrictions upon specific individuals who have consented to be paired up seemingly randomly to share resources which are halved if they decide to remove it.
The issue is that it's inherently a discriminatory act. So if you want perfect equality, you just have to get rid of it.
