Yeah, I agree that contact tracing & testing/quarantining contacts is good, and that presymptomatic transmission is possible.
It looked to me like you were claiming that the hypothesis “stopping all symptomatic transmission is sufficient to prevent the number of COVID-19 cases from curving upwards” has been tested by some countries’ measures and found to be false, and I am questioning that apparent assertion.
