Repealing the law would decriminalize it making it an unregulated activity like being a clown at a birthday party in most states, no licence required. Think Canada from what I understand. Legalizing it would make it legal but only if some certain conditions are met, like to be a tow truck driver you need a DOT heath card, drivers licence and be able to pass a basic background check for the little card that is required. Think Nevada brothels or how it works in Australia where ladies need heath cards and to register. There is a huge difference.
