The point is that superspreader have the same behavior elements of most of the other people on those places, and each of them potentially will go to more big meetings and parties taking few if any measures to avoid keep infeting. You are dealing with clusters of superspreaders, not individuals, that may infect "normal" people as well as not all their contacts with other people will be in big parties.
Good policies to prevent the spreading of the disease should take those clusters and cultures into account.
