That is a bit harsh, as I can easily think of many reasons when you should talk to the police; witness to a murder, rape or robbery, witnessing someone run down a family member, etc, you get the picture.
I get your point but think it best to qualify your remark as “never” is really not your position.
I would not recommend that any client of mine speak to police outside the presence of their laywer, and certainly NEVER completely absent assistance of counsel.
There are too many people in prison today who thought they were "doing the right thing" in speaking to police, perhaps as a cooperating witness, perhaps as something else, that eventually found themselves indicted and then convicted of a crime they didn't commit. It happens, and it wouldn't be hyperbolic to say it happens all the time.
Men died for your right to remain silent, and we should honor their sacrifice by exercising that right, always.
