Wrong tootsie roll. Just because some libertarians want to legalize prostitution, does NOT mean they want legalize SLAVERY. The essence of libertarianism is VOLUNTARY transactions not coerced activities - You’re busted - for lying.
Prostitution is pretty much recognized to be slavery.
The average age for entry into prostitution is thirteen.
The average.
Kids don’t do that voluntarily.
You’re busted, because you can’t claim this is just between consenting adults without supporting adults having sex with kids to produce the suppliers in the equation. It is not just between adults and never has been.
