 Many liberal feminists, too, are opposed to a variety of commodification practices. Some argue that abolition of even voluntary prostitution is necessary to protect victims of sex trafficking, as legalized prostitution may mask continued flourishing of trafficking in its shadow (Dempsey 2010). Others are concerned about the possibility of genuinely voluntary consent in circumstances of poverty or limited opportunities for many women. Several countries that have legalized prostitution, such as the Netherlands and Germany, have engaged in vigorous debates about whether legal prostitution is a voluntarily chosen occupation for many, whether legalization has bettered the circumstances for prostitutes, and whether legalization has been coupled with enhanced enforcement of laws against sex trafficking or other sex crimes. Other countries, such as Sweden, have banned prostitution altogether, spurred by feminist critique of the practice.
