The people who desire to purchase the young do not settle for older prostitutes just because it becomes legal someplace.

Agreed, legalizing prostitution by adults leaves child trafficking untouched. As you indicate, they're separate issues.

They are not. Adult prostitution relies upon child prostitution to funnel prostitutes into the supply.
I have not just my experience, but eight years working with prostitutes from as far away as the Ukraine to draw from.

People choosing to sell themselves for drug money or economic desperation? You get what you get.

Forced prostitution of young people or kids? They can preselect for beauty or some other marketable characteristic. So as long as there is prostitution there will be forced prostitution.
