Well, even with a high test accuracy of 99%, if you start testing 1 million people you will end up having 10.000 false positives with witch you can’t effectively deal.

My understanding is that these assays have a very low false positive rate, globally the concern has been with false negatives. Usually false positives are human error, and retesting (standard practice for this sort of thing) quickly filters them out.

Perhaps spurious steelman: the problem is closure? - Aaah, do I have covid? (takes test, comes back negative) - Whew, I don't. (gets infected) - Hack! Choo! Don' worry, iss not covid, test said I don' have that.

Thing is the amount of cases of covid in the west is pretty small. While the failure rate of the test is pretty high. So testing anyone who wasn't involved with someone with covid most likely gives you a ton of false positives.
