> The infected lab worker causing exactly one massive superspreading event in the wet market without infecting anyone else, That's indeed unlikely, but it's a strawman. As I've noted repeatedly above, most lineages die out. If the introduction into humans occurred outside the market (naturally or otherwise), then it's quite likely that patient infected others outside the market; those lineages just died out. I remember Trevor Bedford showing genomic evidence of all the failed introductions into Seattle before the spread finally went exponential, early in the pandemic. Pekar et al. is basically a more sophisticated version of your argument, with numerical models of the phylogenetic and epidemiological dynamics. I don't think it's convincing (since they chose their power law pretty arbitrarily), but at least they acknowledge and purport to model that stochasticity.
