What Dr. Mina proposed is tests strips everybody would use every day before they go out and potentially spread the virus. These strips are sensitive enough to show a positive result before you have enough of a viral load to be contagious. Get a positive result in 15 minutes or less, and go into quarantine. Ideally, all other household members would quarantine as well, but even if those testing negative left the house, the susceptible ones would test positive before becoming contagious within a few days.

Rapid tests that have to be administered by a certified lab can't possibly be taken by everybody every day. So we would wind up having tests only for people with symptoms. Way too little and too late to avoid spreading. The only useful time for tests is between exposure and symptoms, to prevent the spread. Most of our current tests are done now on patients who are no longer contagious!

The UK has a Tracker App for smart phones, and they get very good participation and compliance. If we created state websites with enough capacity, I think people would comply with instructions to report over the internet. Especially if public health authorities immediately delivered food and prophylactic treatment like high-dose 25-hydroxy-Vitamin D. The website URL would be on the test strip box. And the Vitamin D therapy has the tremendous advantage of keeping the ICUs practically empty.
