You are completely right here!

I understand your concern, but I can readily browse the Web with a muted
sound. In fact, it is quite funny but I very often do so. So I don't really
see a problem here from my perspective to allow the users to disable it.

I suggest not trying to discuss analogies instead of the actual problem [1].
Because then, well, we risk ending up discussing analogies, and we'll loose
sight of the problem...

I am also striving to look for such a line for the last few years. So far,
I find the line to be very non-linear...
