>No matter how much you want find a market effect, it's due to _human stuff_, like people's actual lives and problems. There is nothing even close to an economy around sex

This kind of wishy washy thing I'm sure feels nice to say but doesn't seem to me to have any real explanatory power except at an individual level, which is not what this discussion is about.

I bet you anything that if I had access to tinder backend data and a couple of hours to mess around in Python, I could show you the similarity in the supposedly "non-existent" market forces there to well-studied phenomena in the world of economics and finance. Just imagine a lorenz curve describing the # of "swipes" a user gets!
