This is Moonshot 1 is it not?
I think the idea is that nigh on everyone ges tested with new rapid test.
If negative, it does not mean that you are not incubating it (hence need for repeat, frequent testing), it just means you do not have virus at detectable levels when you trested.
Risk of increase to detectable levels (which is also roughly when you start to test positive) rises over time - probably negligible in the next few hours, but rising, so test every day.
So the community should be safer, as cases will be spotted no later than when they become symptomatic (rather than as it is now, no earlier). And frequent repeat testing means you get everyone who is moving round the city, not just residents
People will do it because it will become a condition of entry
