Just fucking end marriage. It's fucking archaic. When two people become partners they enter a business partnership . That's it. It should be treated as such.
Love and romance has little to do with the privileges granted by the state. Or do you think people should not be allowed to marry if they are not in love?
Sure, that's fine too, but the vast majority of marriages now are based on love. Business arrangements are fine too, they just aren't what people usually get married for.
A wedding and a relationship doesn't require endorsement by the government. Go have a ceremony, grow old together, but you don't need your local county clerk having a say in it.
We should end the legal institution of marriage. It literally only provides two benefits: you can pool income for tax purposes, and you can share health insurance. Both of those items could easily be addressed without marriage, especially if we had universal healthcare or if you could add a partner to your health insurance like you can with car insurance.
Meanwhile, marriage in it's current form means that the state decides how much of your retirement savings you get to keep when your partner decides to leave you or you decide to leave your partner. It's the worst financial decision that it is possible to make to ever marry someone outside of your class because of that risk, and that risk sucks the joy and romance out of the whole thing.
If you want to have a fairy tale wedding or an important religious ceremony, go for it, but there is zero reason to get the government involved at all anymore.
I happen to agree, me and my wife lived together for years before getting paperwork done. Just finally had to do it, it is just too much work otherwise. From insurance, to property, to inheritance, to medical decisions. A justice of a peace simple thing.
