"Should prevent" is not very definitive for such a dire action. I don't agree with Yukon's delivery but his message is somewhat correct. Do your own research and hear all sides and get a true understanding of the virus and what it is.
If you think that social distancing is the only solution after all of this, then that is your opinion and I will respect it.
I personally do not subscribe to that concept for the l long term, but it will definately help today with the hospital overload since it is novel and we are learning more everyday on how to treat it and even effectively diagnosis and test for it. We make exponential progress everyday combating this novel virus and we will reflect on these interesting weeks/months and learn how to better react in the future as there will be more viruses in the future that will be novel.
