It was you who first mentioned supply and demand.
Yes, an oversupply of girls relative to the demand, to explain why despite “an adequate supply of dates”, some girls will date much less than others. Admit that you don’t understand, instead of endlessly repeating your mantra,There is no shortage of dates available and yet many girls suffer from “infrequent dating” despite their being a mire than adeqyete supply.
I’m not sure what you want with the rest of your post. Will these things create more boys, hence more demand?
