It's not, yes. But:"Trust me bro, don't " isn't going to be terribly effective if they don't see another way forward.
1) I think you are strongly underestimating the impact a 15+ successes quality education and indoctrination material can have on someone. It should be well beyond "having a religious experience that completely changes one's life" level.
2) It's not going to be effective if they don't see another way forward. Correct education would expand the audience's range of possible solutions to situations they find themselves in, and prevent them from using the Lawbreaking (or other bad) option when there are alternatives. Just because the solution isn't perfect, doesn't mean it's not good or isn't worth implementing.
Again, we have a very different view of what 15+ successes educational and indoctrination material carefully prepared by a celestial exalt is, and how it would impact a young teen going through a trying time of their life.Based on what? Giving people the ten cent tour of the laws is the same as saying "just say no to drugs". The laws of magic aren't exactly covering a whole bunch of stuff people will fall knot just fooling around. It's stuff like murder, mind control, and forcibly shape shifting other people.
People break it in ignorance of the backlash, but not just because their other plans fell through one weekend. Telling them it's dangerous and has consequences isn't a deterrent for the desperate.
Also, Laws also cover healing (falls under changing others), including stuff like scar removal, spiritism (summoning unwilling dead), telepathy. Even the best kind of education and indoctrination wouldn't help everyone in every situation. But it will help many.
This breaks at "go into a community" step. We know that there is essentially no community in a number of areas and for a number of groups. Charity fell into a cult because she didn't have a reliable source of information. Elaine was adopted because of her noticeable magical talent she knew nothing about. Order of Cauldron was, until recently, a female-only organization, and there is no equivalents for young males in Chicago area. I am willing to bet that a large number of practitioners either have no knowledge of the laws or White Council until Wardens break down their door, or have a very distorted view of them, possibly coming from the mouths of the fae and the like.The white council doesn't post videos online, but they do make a point of the laws in most interactions with minor talents. Go into a community of low key practitioners and they'll at least know what the laws are, and that's where most minor talents come from.
We have a very different view on education. You seem to view it as information only. It's given to the recipients, and they decide freely based on their own biases how to use the information. I view it as inseparable (unless specifically desired, which is possible, but very hard) from indoctrination, where the teacher's biases affect the students in regards to the knowledge being transmitted.If it's publicly available idiots will use it to get into trouble.
You give a fae dealing survival guide to people and half of them are going to take it as a warranty that it's safe to do so even if you repeatedly say otherwise.
Magic lessons from my perspective are a complete nonstarter for anything public facing. It's almost guaranteed someone will build themselves a pipe bomb equivalent with it.
If we, at 15+ successes, concentrate on how "if you break these rules, you'll lose SAN score, always, no escape, and the best and only hope for you would be to immediately call me / authorities" parts of the laws, I am fairly sure most, if not all mortals, would internalize it.
Though shalt now transform others is the one I would be most worried about. Cosmetic adjustments (hair dye magic, nail painting, etc), minor healing (scar removal, flu control, etc) all sound like good things. And they aren't.The fourth law, mind control is something that could easily be triggered in a non serious way. Some kid thinks they are Obi Wan Kenobi and makes his teacher forget about the homework they did not turn in. Then we have invade the mind of another also sounds very grave when you put it that way, but then some kid thinks he is the star in What Women Want. Popular culture is filled with examples of fictional people breaking the hell out of the Laws of Magic. Other than the Law against murder and necromancy none of these have strong cultural taboos for someone who has never engaged with the supernatural.
