What you have continuously failed to comprehend is that not everyone is attracted to the same thing.
It would be interesting to get data from a site like tinder or POF and see. I am willing to bet that there is an exponential curve with the most popular 20% of both men and women getting the lion's share of the interest.
In real life you choose among the ten or maybe twenty women in your social circle who are available, but online gives you the illusion that you can pick anyone. So people reject partners that they might have considered worthy from a smaller sample.
I would also expect the data to show that women are choosiest, showing an interest in a smaller sample of men, while men message on a flatter curve, sending messages to a larger number.
