You really need to keep up with the literature. A paper recently came out which says it can survive ten days at ambient temperature a on most plastic and steel surfaces. And others have reported it is aerosolized. It spreads through cough, sneeze, and breath.
Edit: I found this literature review [1] that sounds similar to what you're referring to. Note that this is only a summary of previously published results on similar viruses. If you check the source data in Table I the persistence times are from hours to days, and the author's conclusion is "up to 9 days" (emphasis mine). In my opinion this is very weak evidence to say that it can survive 10 days "on most surfaces".
Perhaps if your church likes to pack in people so closely that they're touching and thinks that it's your duty to God to repeatedly drag yourself to church no matter how sick you are. (The likely index patient apparently attended services 4 times after symptoms started.)
Afaik none of the churches where it has spread were the sort that has that kind of a practice — more pentecostal or cults. (Cults who knows, they could do that. But pentecostals ime don't much like wine and I've never participated a recreation of the last supper when I've been to a pentecostal church.)
It's unlikely, wine's alcohol content is only around 13%, you would need about 4 times that to kill the average virus. It would also be on the lip of the cup rather than in the wine.
You could ask the same of many of the responses. All of your examples are "strong" responses that reassure the public, like the flight restrictions which public health experts have argued against. By the way, public transport is, and has continuously been, running in most cities in China, and people in many cities (I have direct knowledge of Beijing, Shanghai, Guangzhou, Shenzhen, Zhuhai) are now slowly returning to normal life.
Because they're an authoritarian state, grasping at straws, and they can. The new politicians in Wuhan are connected directly to Xi, and they're doing all kinds of stuff that has no scientific basis, just to be doing stuff.
There's no evidence that you are remotely likely to catch COVID-19 by doing any of those things either.
