You missed the other commenter's point entirely. They're referring to the total size of the dating pool and the need to filter that down to something that is both more manageable to interact with and more likely to lead to interactions with interested parties. The goal shouldn't be "as many dates as possible", rather "as many potentially compatible dates as possible". Without winnowing down the size of the potential search group, one would be far less likely to have a meaningful, favorable encounter on any hypothetical date.
