Socially expensive, not financially expensive; it’s kind of theoretic either way, because if we posit a society in which “No sex before marriage” is the standard, we might as well posit a society in which polyamory is the standard, but in the case of such a society, there would be less resistance to casual dating.
a society in which “No sex before marriage” is the standard
That seems an unfair comparison, since, as far as I know, there actually ARE quite a few examples of that, both historically and currently. I’m not aware of anywhere near the same level of polyamory-as-standard (it generally seems to be polygamy or some other variant where high status earns you additional mates, rather than the “Bay Area” style of simply dating multiple people)
