If someone needs to sell sex because they're poor or because they're homeless or because they're undocumented and they can't find legal work, taking away that option doesn't make them any less poor or house them or change their immigration status.
Si alguien tiene que vender sexo porque es pobre o porque no tiene hogar o porque está indocumentado y no puede encontrar un trabajo legal, quitar esa opción no lo hace menos pobre ni alojarlo ni cambiar su estado migratorio.
