Indeed. I had coffee with two friends and one asked for a referral for a good teacher for the fellow that replaced him in his high level executive job. My other friend went on to say there were many good teachers around and to just get one in the area, you couldn't go wrong. I almost had an apoplectic fit.
The questioner then looked at me said we would meet with the young fellow next week for a some suggestions. I told him if the teacher is not well versed in the works of Homer Kelley, run away.
We will be having coffee next week and then an appointment with Mr. Carter should come next.
Point being, there are many teachers of golf. There seem to be very few teachers of G.O.L.F. The difference is enormous.

There are many good players - and they have had different instructors and coaches. If you have a lot of talent, I guess there is a good chance that you will be a good player in any case. It's worse for the average player, with average talent and who perhaps never played in younger years. Then it's not enough for a instructor with a method to say to the player who needs instruction : do it like this. The good thing with TGM is to find what's best for you. Reading the book to find this may work for some, but it's far better to find an AI who can help you work this out based on all the information in TGM and what it has to offer, which may differ from player to player.
