The editorial is B.S. It says that anyone doing any barbering, hairdressing, or manicuring to friends or family in the privacy of your own home is breaking the law. Bullcr*p! It's if you do it for PAY that you're subject to licensing. Same applies to lots of other activities.
It's true that it's misleading in that respect, however, the law is still totally idiotic. There is no danger to the public from people setting up a little business to do manicures without 300 hours of government-approved training. These laws exist ONLY to fatten the pockets of the schools providing the training -- those schools lobby politicians and donate to their campaigns in order to get these stupid laws passed.
