Honestly, the levels of desperation and despair I'm seeing in the hellscape that is modern dating, I think a lot of people would sign up for this. I probably would if I were single. It's very similar to how matchmakers work, and they're popular all over the world, and have been for millennia. They're an unbiased and impartial judge and coach. We all have enormous biases and weaknesses in so many ways, and we could all do with help to better ourselves.
The important distinction here is no one is forced to marry anyone. This is entirely optional.
