I think we need to be realistic about containment. A full lockdown until a vaccine is released is the safest option, but it isn’t a sustainable strategy.

The main thing we should focus on is keeping high risk people away from people likely to have active infections, determining hotspots/where to increase/maintain blanket lockdowns, and detecting people with active infections early/getting them to self isolate when they’re just getting sick.

If someone really wants to expose themselves, there isn’t much you can do to stop them short of martial law, which starts a feedback loop of escalating civil unrest. I think you’re likely to have more success keeping people worried about being infected away from people who either don’t care or have antibodies than keeping all the people that want to go out indoors for a year.
