在沒有參雜其他因素的情況下，性交易本身對於他人無害，所以法律上或甚至道德上都沒有禁止的理由。性交易對於兒童或少年可能造成的傷害，狹義刑法已經有完備的防制規範，因此兒童及少年性交易防制條例實質上的意義僅存於剷除性交易意識。然而，既然性交易應該是合法的工作型態，性交易意識的淨空就不再可能是刑法概念上的法益，而此一條倒的正當性基礎也已經蕩然無存。

If we leave other relevant issues aside, the sexual transaction itself is harmless. Therefore, it is not justifiable to prohibit the sexual transaction either in law or in morality. As to the harm the sex transaction can bring to children and juveniles, our criminal law has already had a thorough preventive system. It thus leaves the Child and Juvenile Sexual Transaction Prevention Act the only role to deter people's desire to engage in this kind of transaction. Since the sex transaction is lawful, to deter the desire to engage in the transaction is inconsistent with the goal of the criminal law. This act has consequently lost its legitimacy.
