If guy keeps ghosting a lot of women, women will see him as more attractive due to massive abundance.

You are getting down-voted, but "playing hard to get" has truths in it. The women I rejected keep coming around all the time, whether it is month later, or a year later. That said, I was not intentionally playing "hard to get", it was a genuine rejection. It probably hurts their pride though, especially if they are not used to being rejected.
