The super-spreader hypothesis is faulty. Sure, there be such people who shed virus like a fountain, but that theory discounts the plain vanilla person who infects two or three other people the same way that the other coronaviruses (common cold) get spread. Super spreaders are likely rare, amd add a small fraction to the underlying R0 value rather than be responsible for the bulk of the infections.
The super spreader theory also ignores the effects of one host be in close quarters with lots of other people. Anyone can be a super spreader given enough proximity to enough people. One bright spot is the Chinese habit of wearing a mask when ill to prevent the unchecked cloud of virus in every exhalation. That particular habit is something that the government would be wise to promote on TV etc.
