"Suppose I say, "The supply of young men available as sexual partners to the women of France after World War I was sharply limited". Does this imply that I think the young men were sitting on a shelf ready to be bought as meat by the women, or that they were looking for nothing but an appropriate organ to stuff their vaginas with, or that it was a matter of cold economics with no passion involved?"

Yes. Talking about them as a "supply" is commodification plain and simple.

In the realm of consent and choice, the "supply" might not choose to want to be supplied.

In your above example the numbers alone determine the supply. The number of men vs the number or women.

Historically such numbers almost always forget the major stumbling blocks such as the fact that we must presume a not insignificant yet unknowable number of closeted gays and lesbians. Choice might allow them to remain closeted, but their inclusion in a "supply" of heterosexual partners makes what should be a private choice into a matter of public policy.

Further when we talk about them as sexual partners we aren't allowing the biggie, lack of consent to be used as such for other personal reasons. Supplies exist to fulfill a need. You have carefully chosen the terms of supply and demand. But only to a hardcore Stalinist do people exist as commodities this way to be allocated by need.

When the "supply" necessarily includes those who would rather be celibate than have sex without love, then it suggest state-sanctioned rape as the way of matching supply and demand. And without the rape, then you cannot know, before a choice is made, whether someone will choose to be a part of that "supply."

I'm really surprised that you can even claim that the commodification of sexual partners is "neutral" regarding any worldview that values choice.

But OTOH, you thought that your claim that girls with agency would all want to be prostitutes was reasonable too.

You see commodified sex everywhere you see choice. I'm just not that misanthropic.

But then again, I live in a world of consent where nobody ( adult ) has chosen me in over a decade. I know that its not about the number of females, and that they don't constitute a "supply" of anything for me. Their choice is theirs.

Strangely enough if you try googling "supply" "of" and "sexual partners" you find an overwhelming number of links about narcissists. Another term that's value neutral ----- so long as you're a narcissist.

Me, I think of the "comfort women" of WWII. They were supplied to meet a demand. And there the suppliers ensured that the available supply of women supplied what they were there to supply: sexual partners State sanctioned rape victims.
