I know, I took a peek at his course listings. I think this is sort of besides the point; he doesn't specifically advocate that your average citizen needs these classes. I think trainers can provide whatever the hell kind of training they want so long as they aren't misrepresenting themselves or the curriculum. At the least he has the real world background to teach these things, unlike some others, and I'm sure there are private security types who could use this kind of class.
I think he has a point when saying that firearms training is not really the same as other free market scenarios. In the case of "tactical" firearms training your life may be staked on your training, and if someone exaggerated their experience or their credentials then in some way, they may be responsible for your unfortunate demise if you fuck up for real. If I got shot doing something I learned from a fraud I certainly wouldn't be very happy! If an instructor claims to teach "tactical" shooting classes the implication is that they're teaching combat relevant and vetted technique. If I ended up getting something that is totally untested except in Instructor Zero's backyard, that seems to be somewhat problematic.
While there isn't any governing body on what is "good" technique in shooting, I think there should be some level of self-regulation in that instructors need to be careful of overstepping the bounds of their experience. For example, I wouldn't want to learn "tactical" shooting from Cory and Erika and I don't think they would be morally correct in offering "tactical" shooting classes without input from someone who's actually vetted the techniques.
