Several nations have legalized prostitution in ways where you can be a prostitute in business for yourself, but can't have someone above you taking a cut. This has the downside of preventing prostitutes from banding together to share rent for a space but it does a lot to limit pimping. Further improvements to the law could potentially allow for shared rental agreements of various types as long as there isn't someone getting a % cut and that would still effectively keep pimping illegal.
