So I guess I'm really confused about your question, then. Are you asking about what the end game is, or are you asking for security and certainty? Because the former is massive drop in new cases, and the latter is just not possible. Infection is always a numbers game. You wash your hands, not because it will 100% eliminate all possibility of the virus living on your hands, but because it significantly reduces the microbes on your skin and reduces your total chances by a measurable amount. It's not perfect, but it's enough to matter. You ask people to socially distance, and you put in place things that enforce that like closing restaurants, bars, and schools, not to create a 100% reduction in transmission, but to significantly reduce it. And so on. This is and always was a numbers game, with huge amounts of uncertainty. And the reason for social distancing is, as you say, because of asymptomatic transmission. It helps, but it's not a panacea.
