ZD, there are halachos of tochacha. When we should try is not based on how we think it should be, but on what the halachah is for that situation. I’m glad you’ve acknowledged that not only rabbonim can give tochacha. Maybe at one point you’ll also realize that you don’t have to be 100% certain that the person’s behavior will change immediately for the mitzvah to apply. Gentle rebuke over an extended cperiod of time has often led to improved behavior, and sometimes immediate improvement.
