I would disagree. My reasoning is that hacking something apart, doing damage, bending bars - these are all strength based. It is a physical interaction between an individual and a physical object.

Intimidation is not about "can I bash your head in" (which as you point out, Strength could speak to) but "you can avoid getting your head bashed in if you do this thing for me" which is a communication interaction between two entities.

I could see the idea for the "bash your head in conversation" to get a bonus if the person was huge, but then I could make a situational case for pretty much any stat, class or proficiency. But it's based on communication and interaction - and that - in DnD, is represented by Charisma.
