I don't think it's that simple. Marriage isn't just about sex, after all. Some couples love each other and want to be together as companions, but sometimes the dynamics of the relationship changes over time. What if there is a huge rift between one partner with a low libido, and another with a high libido? What if due to a disability, one partner isn't accessible sexually anymore? What if your sexual interests change over time, and your partner is not into it? Should you just feel frustrated and resentful? Maybe eventually have an affair to have your needs met?
I don't see what is wrong with two people agreeing to have an open marriage. As long as all parties involved are aware of what's going on, the terms have been discussed and agreed upon, and there's open communication and empathy between the couple if the terms ever become disagreeable, then who is it hurting? It won't work for everyone, but for some people, it does. Sometimes it saves marriages.
