It's interesting you should choose taxes in particular for your analogy; by trivial extension, you cast 23andme as someone who operates as a tax accountant not merely in ignorance, but in outright defiance, of the professional licensure requirements of the field. Libertarian-utopian notions of needless regulatory immurement aside, such requirements exist for reasons amply evident in a study of their origins; in short, without a licensure requirement in such a highly specific and technical realm, incompetents and charlatans of every stripe abound, to the ultimate and severe detriment of all those who would seek the advice of genuine professionals in the field.
