Same on laptops, if i'm in a coffeshop and forgot to turn the volume down and suddenly some video starts playing at full volume, i want to be able to quickly turn down a physical dial to zero, that would take me under 0.1 seconds. Not press fn+F11 ten times which takes almost a second.

In general, I agree, but that is the use case for the mute button.

Which is also digital! Fumble for the fn and esc keys as music blasts out of your laptop and people turn around to look at you.

Bonus points if the software the receives fn key presses don't work instantly, and there's a half second lag, during which you mash the keys again and negate the mute.
