And when he finds out later in life that it was just propaganda, his trust in you and any warnings of a similar kind will go entirely away. Which carries a massive e risk of doing the exact opposite of what you intended (despite the advice itself, at the core, being pretty decent).

Case in point, the massive failure of D.A.R.E. drug abuse prevention programs for children and teenagers in the US. Yay propaganda.

Turns out that even when the advice itself is decent, you can easily sabotage it all in the long term by using those types of propaganda methods. All just for a short-term “win”.
