Reduces the number of 'sex tourists' travelling abroad to use brothels/services that disproportionately exploit children and force them into sex work

The argument

This argument for full decriminalisation holds that legalising sex work at home reduces the number of 'sex tourists' who travel abroad — and so reduces the demand that fuels the exploitation of children and trafficked people in the destinations they visit. The reasoning concerns where demand goes when it is suppressed at home. Where buying sex is criminalised or heavily restricted, some buyers travel to countries where it is more available, cheaper, or less policed — and the destinations that attract this trade are frequently those with the weakest protections, where demand is met through the worst abuses: trafficking, coercion, and the sexual exploitation of minors. The sex-tourism economy, on this view, channels demand precisely toward the places and practices that harm the most vulnerable. A safe, regulated, decriminalised domestic sex industry gives those buyers a lawful option at home, drawing demand away from exploitative foreign markets and the abuses that supply them. The protective logic is one of harm reduction across borders. Demand for paid sex exists and does not vanish under prohibition; the policy question is whether it is met in regulated settings where workers are adult, consenting and protected, or exported to unregulated ones where it funds child exploitation and trafficking. By satisfying that demand domestically and lawfully, decriminalisation shrinks the flow of sex tourists abroad, and thereby the demand-pull that drives the worst exploitation in vulnerable countries. Reducing the customer base for overseas exploitation protects its potential victims. From this standpoint, a lawful home market is a tool against exploitation elsewhere. Because full decriminalisation reduces the number of sex tourists travelling abroad to use services that exploit children and trafficked people, this argument holds, sex work should be fully decriminalised.

Premises

Counter-arguments

Critics reply that the displacement mechanism is asserted rather than evidenced, and may run the other way. There is no body of research showing that decriminalising sex work at home reduces citizens' travel abroad for commercial sex, and the drivers documented in the sex-tourism literature — cost, anonymity, and demand for acts or for persons that would be unlawful anywhere, including minors — are precisely the ones a lawful domestic market cannot by definition supply. A buyer seeking a child is not diverted by a legal adult market. Cross-country research also cuts against the premise about volume: several studies associate legalised sex industries with larger rather than smaller inflows of trafficking, on the reasoning that a legal market expands total demand and supplies cover for coerced labour. That finding is contested, but the argument does not engage it. Critics add that the remedy is located in the wrong jurisdiction: destination countries have their own laws and enforcement capacity, and extraterritorial prosecution of sexual offences against minors committed abroad, which many states already provide for, targets the harm directly. The sibling positions note further that this line would justify a domestic market on grounds unconnected to the welfare of the people working in it.

Rejecting the premises

[Rejecting P1] The displacement claim is asserted rather than evidenced: the drivers documented in the sex-tourism literature are cost, anonymity and demand for acts or persons unlawful everywhere, which a lawful domestic market cannot by definition supply. [Rejecting P2] Granting that destination countries host the worst abuses locates the remedy in the wrong jurisdiction — those states have their own laws, and extraterritorial prosecution of offences against minors, which many countries already provide for, addresses the harm directly. [Rejecting P3] Cross-country research associating legalised sex industries with larger trafficking inflows, on the reasoning that a legal market expands total demand and supplies cover for coerced labour, cuts against the diversion mechanism the premise assumes.
