You have showed that it is unnecessary in one particular (very simple) case. However, you have not showed that it is unnecessary in all cases, so this is not really relevant (had we been talking about a human doing this, you'd have a point of course).
I suspect that mathematical thinking is not your thing - no problem. For otherwise it would be clear that the 'simple' example I provided covers the general case. Let me try again. I write a PA-aware sound app X that * always sets its volume to 0 dB (max). * always outputs silence (zero valued samples). As soon as that app runs, PA will set the master gain to 0 dB and use software scaling on all other apps. Now there are two possibilities: * Either everything is OK (it will be), and we have shown that you can always leave the master gain at 0 dB, * or everything is not OK, and we have shown that PA fails.
