I do see some value in having the state license people who make a business of convincing strangers to allow them to use sharp cutting implements on their body in ways that, if not properly maintained and used, could lead to injury, to undesired slow-to-reverse harm to appearance, or to transmission of infestations like head lice. There's plenty of room to disagree on what the specifics of this oversight should involve, but some degree of pre-approval seems very much appropriate.
