What's more, using your analogy plugging and unplugging anything in a USB

Baloney yourself. I have worked on a PC where the unplugging /
plugging of the speaker jack "burnt" the sound card. Whenever a
"powered" device (powered speakers) there is a small chance that the
power / ground is not correct.
would damage the USB circuits.
Yes, there is a "small" chance to damage the speakers. But, there is
also a chance to damage the speaker out jack and the sound card. The
audio cable has power and this power is just enough to possibly send a
"power spike" (too much power) or a "power brownout" (too little
power.) These "fluctuations" can be enough to "burn" the sound card
audio processor / jack.
