If you're complaining about reusable bags at the store, you should take a good long think about every questionable surface and hand those groceries touched on the way to the store and your cabinet.

In regards to the questionable surfaces I don't dispute that either but it is irrelevant.
what the relevant issue is measuring the baseline transmission effectiveness from a outbreak source prior to the behavior change vs after.
It is a physical fact that a shopper, for example a horder, who can provide source bacterial matter has been increased in likelihood to bring a bag with such matter and then when checking out has an exponential increase in contact with others. There are documented cases of people using hospital bags for their groceries.
