Laura is a complex character: She wants to earn money and she doesn't feel guilty to offer sex. However, she doesn't really enjoy the moments with their clients, especially with whom she doesn't like. From the moment she is being ripped off (i.e. Clients fail to pay, clients force her to perform some sexual acts she doesn't want), she is somehow regretful about doing it. In the final scene where she takes off her glasses and wig then smiles, showing who she really is. She is kinda showing us that she is glad she is no longer a sex worker, and she didn't make a bad choice to be a sex worker. She didn't choose to run away, instead, she embraces it and lives with it.
Perhaps if she wasn't a sex worker in the first place, she would't discover who her bf really was and how amazing her life would be without him. Study, work, and life. Husbands, boyfriends, they might just haul you somehow. Perhaps if she didn't choose to come to Paris after the bad experiences while being a sex worker, she would't recover it from her nightmare. Everything happens when it is supposed to.
