I agree.

Acoustic is ideally exactly that. Once the audience or room is too big for comfort, electronic assistance is needed - both from the listeners' and the performers' points of view.

The point where it becomes 'electric' is where the 'sound' has priority over audibility - in other words, the P.A. isn't there to help people hear, or to avoid sore throats, but it is needed to obtain a specific effect.

That doesn't necessarily mean it has to be loud, though...
