Look, MOST people can't afford to be off work UNLESS they are sick enough to get sick pay.
You can't expect anyone to fail to pay the rent and risk being homeless. Same with utilities. You can't expect them to risk being cut off. So unless it is OBVIOUS they have the virus, yes, they'll be out in public.
If you want to avoid meeting the virus, stay indoors where YOU control your environment. It's the only way to be safe.
So unless the government steps up and says, NO ONE can be penalised for taking 2 weeks isolation, by banks, utilities, landlords, those on low incomes will continue to be out in public, unless they are at deaths door.
Perhaps that is what DC and BJ are doing? Drafting a war plan. IF DC has any common sense, that is what he will do.
