I think a big part of the confusion here is how do you clarify the meaning of R0 versus Rt in a context where people don't know the difference, and are using R0 in a context where there is either a time component or obvious public health interventions.

R0 may be a weak theoretical construct, but saying that it's also contextual and not inherent to the virus doesn't do much to clear things up.

Thanks for pointing that out, I corrected the post. It wasn't really important to my point though, which is that we might have enough immunity to let the infections die without football games, while we still have growth with football games.

It would have been more effective if you left it at that. I'm trying very hard to bow out of HN discussions on COVID, you were making a good point in a bad way and it would be a waste to see it lost. Thank you for the correction.
