I just bought a battery powered lead blower from Costco. It's my first one and it's awesome! I use it all the time for things I didn't think I would.
However, it is still very loud and doesn't last long enough for commercial use.
One instance recently, had a few very aggressive wasps in the garage (Son is allergic). In the past I'd use some chemicals, the leaf blower got them out in seconds, it's so powerful it blew them outside far enough they couldn't get back and just flew off.
Inspirational words, but I'm not giving up my power drill. Long ago my family had a brace and bit, but it's long gone, and would be awkward to use where I use the drill.
I'm a bit frightened to ask what surprising use cases you found for a lead blower.
On a more constructive note, I don't know where people get the idea that battery powered means quiet. My vacuum is electric and far from quiet – why would a leaf blower be?
It just is. You don't need a theoretical explanation, just go turn on a gas leaf blower and a battery operated one and see for yourself. The internal cumbustion engine is much louder than the actual blower mechanism.
