You have to know this is already going on.
Yes, of course.
I see the argument of saying when something already happens we should apply regulation and provide a framework for checks and balances, but by doing this we also legitimise the process, by recognising it as a legal and morally fair and sound way to make money. This can apply to all kinds of debates, from the legalisation of marijuana to prostitution.
It's the age old argument of what we accept as being adults making autonomous decisions, (within a patriarchal society where we understand women can make money from their bodies) against whether we say women shouldn't be able to use their bodies to make money as that is morally rejected, (as women are human beings and not a collections of body parts to be shared, sold, penetrated milked or harvested for organs or eggs).
For me, in this area specifically, this is on a scale of milk and eggs being harvested (milk and eggs...already sounds like a farm) and sold, to live uterus implants, to the renting of woman for surrogacy and the sex trade.
Though women are involved in these processes there is always a man, somewhere at the top making all the money.
