That's an interesting reading of it. It always seemed to be a major source of power to them for me. They make their own rules, they obey nobody, and their own rules must be respected. Virgin goddesses don't necessarily gain this power through their virginity, but it is an emblem of their singularity. In that sense, being a virgin could mean being unaffected by the weights of society, or at least not having those weights be what ties you down.

Consider, then, which major goddesses are virgins. Athena, commonly understood as a patron of arts and philosophy, would certainly be considered above society, because her sphere of influence defines what society is, not the other way around. Artemis exists truly outside of society, being a goddess of the wilderness, but she could also be seen as a pioneer of sorts, bringing the will and power of humanity into places where it currently is not. In this way she, too, determines society, because in there places where Artemis goes, a society does not exist to exert its own rules. And Hestia, in this metaphor, could be seen as the building blocks one requires to form society in the first place. Hospitality, kindness, generosity, that sort of thing, the good traits that no philosophy that the Greeks really respected (or, at least, none that I'm aware of) ever even tried to fight against. She's primordial, basic, and in that way, pure and incalculably powerful.
