I think the freak outs are the point.
It brings me back to something I've been curious about re: contact tracing - what's the correct amount of contact to count or be traced? There can be whole days where I don't have any irl contact with anyone I know and could provide info about, but do have contact with strangers like people I end up stopping and talking to while walking the dog or people I end up closer to than I'd like while in my building (say, delivery people or contractors, not even neighbors whom I could eventually figure out) or randoms in the grocery store.
I think if I tested positive and was asked who I'd had contact with for a week or so, I'd usually be able to name one.
Contrast that with the exponential network of randoms who'd dined in a place I did over 2 weeks.
