I don't think we'd accomplish a truly sterile environment. Even the places with good ventilation and far-UVC light won't be truly sterile. If someone coughs right at you, you are sor gonna get exposed. There will also still be plenty of places where we won't do these things. Most people won't have this in private homes for example. I think it would bring urban areas maybe somewhat closer in exposure levels to what you have in more rural areas.
