People are contagious a few days before they show symptoms, but most infections are by unambiguously symptomatic people, because they carry the highest viral load. If symptomatic people stay home you cut down infections by 2/3rd if not more. R0 goes from 1.5 to 0.5 and that's sufficient.

The work you cite is speculative.

> Available evidence from contact tracing reported by countries suggests that asymptomatically infected individuals are much less likely to transmit the virus than those who develop symptoms. A subset of studies and data shared by some countries on detailed cluster investigations and contact tracing activities have reported that asymptomatically-infected individuals are much less likely to transmit the virus than those who develop symptoms.
