> contact tracing and isolation of positive cases

That works if there is a relatively low number of cases, or you have enough testing capability to carpet bomb everyone with tests.

Once the number of cases gets too high, contact tracing has lost, because you have too many unknown cases in the community.

If you can’t test a large percentage of your population, you can’t detect pre-symptomatic or asymptomatic people that are spreading the virus.

Yeah, my jurisdiction has a pretty high test rate (3800/million people), but there's community spread, and they've explicitly stated they will not have the test capacity to test everyone who's symptomatic in at least the short to medium term.
