Not sure why you got down voted, I can only agree.
Social distancing only slows distribution it doesn't prevent it reliably also some disease are spread by animals which are not at all affected by social distancing.
And then vaccines are also not enough as it had shown for some disease where we did try to eliminate them by handing out free vaccines in affected countries.
Lastly social distancing has a super high cost if continued. Not only economically but a super high health cost. Humans are not meant to live permanently social distanced they are inherently social animals and the internet can't really replace it. E.g. for people fighting depression social distancing can be like poison. It prevents them or at least restrict them from doing many the thinks which can help fighting depression and causes "physical" isolation (Internet is helping but has limits, it's not helping enough to counter it). Another group most likely majorly negatively affected are people with "home" problems, like violent partners or parents (or just to controlling partners or parents). To just name some example.
