Not sure, the point.
People generally aren't complaining about home owners mounting cameras for themselves (the car is no different). A 3rd party combining the interconnected nature of their system into a holistic system with sweeping coverage is much different than a single person figuring out who hit their car.
It would be nice for neighborhood cameras to timely alert neighbors when a porch pirate was on the prowl in their neighborhood. I get the privacy implications, but after having a few packages stolen one might just not care anymore.
Since police absolutely have no care about porch pirates where i live, I rig my camera to turn up a siren for 10 seconds (using a homekit power plug) when it sees someone near my townhome after 11PM (this is enough to usually scare them off to easier pickings). It wouldn't be so bad if the kids bedroom wasn't on the first floor and we are on the third, but it is what it is. At least its only really bad in late spring and summer, the only time when Seattle's long rainy season comes in useful.
Its too bad that I can't bike in Seattle anymore, the theft situation just makes it too unbearable (and probably why you see fewer people biking these days even though they are dumping lots of money into biking infrastructure). Think what we could do with cameras like we've done with apple tags to ramp down bike theft (then again, police don't care, and people aren't ready to go vigilante here).
