> But COVID-19 also has a _very_ large incidence of asymptomatic transmission

Does it? Meta-analysis concluding secondary attack rate in households from asymptomatic transmission around 0.7%.

> Household secondary attack rates were increased from symptomatic index cases (18.0%; 95% CI, 14.2%-22.1%) than from asymptomatic index cases (0.7%; 95% CI, 0%-4.9%)

Yes it does. The disease would have been eradicated a long time ago if it didn't have asymptomatic transmission. (see: SARS and MERS)
So you're saying the studies are all wrong based on your a priori reasoning that interventions so far have failed?

Make a convincing study to disprove them.

Asymptomatic transmission might be not very high, but presymptomatic transmission is very high. It is well established fact, that people are the most contagious right before onset of the symptoms.Keep in mind that the symptoms might be very mild.

Actually if you read the meta-analysis I linked, 0.7% secondary attack rate covers both presymptomatic and asymptomatic.

MERS has not been eradicated.
