 Perhaps this view is correct. Bracketing arguments based on externalities, it seems perfectly plausible to maintain that the state is justified in interfering with transactions only if one party is violating the other’s rights. That said, those who invoke the concept of exploitation frequently maintain that such exploitation provides a reason for state intervention. For example, when it is claimed that commercial surrogacy exploits the birth mothers, the critics typically argue that surrogacy contracts should be unenforceable or entirely prohibited. Similar things are said about the sale of bodily organs. Those who make such arguments do frequently claim that the transactions are nonconsensual or harmful, but they seem prepared to make such arguments even if the transactions are consensual and mutually advantageous.
