The lockdown idea is appealing but the devil is in the details, you have to limit group sizes. If the transmissible window is say 3 days, and the group size limit is 5, that's a 15 day lockdown. In practice big households are impossible to limit so in theory if you don't lock down for O(household members) you waste time.
