In many European countries it's legal and it's safe for sex workers. These women need protection and a more respectable working environment. As someone else mentioned, the women are in a desperate situation where they have little to no other options for making a living. In many cases, sexual services have a beneficial therapeutic value mentally and physically for people and so, I believe there is a legitimate need and benefit to society if it's done properly. In the current situation where it's not legal, assholes feel emboldened to abuse these women and rob them. At the very least, these women need to be able to comfortably call on the police for help. Legalization & regulation is a decent option. Your wallet and "need" for cheap sex is definitely not the most important thing here. These women are humans with feelings and families and a desire to have a better life. Think about them for a change.
