If there was a single report of exactly one of the scenarios I described, I would have more doubt about fomites not being an issue. Ideally there would be more than a single documented transmission event. If fomites were a thing, you should see contact tracing coming up with things like "the delivery driver dropped off 30 packages and 6 people got sick" or "the chef at a takeout restaurant packed up 30 orders and 5 people got sick." I've never seen anything like this though. At this point, a year and 100 million cases in, absence of evidence is evidence of absence.
