Roll a dice representing all the locations of possible human bat interactions. How many of those land next to research labs that study this.

That's not the correct calculation because you've selected the research lab hypothesis post-facto. The correct calculation is to roll a dice representing all the locations of possible human bat interactions and see how many of those land next to some landmark that you can form some sort of conspiracy about.

You may be misunderstanding expert opinion in prior elicitation. Many labs in the last century have had lab leaks. https://en.m.wikipedia.org/wiki/List_of_accidents_and_incide...

And if you add all the sane hypotheses to the equation, how many would that be? 2?

The only thing that evolves faster than this virus are the conspiracy theory memes[1] that the internet collectively weaves from circumstantial evidence where more and more compelling narratives become more and more widely shared. I'd wager that 100% of pandemics, regardless of origin, will have some compelling conspiracy attached to them. Compelling conspiracy theories is what the internet manufactures, particularly in the absence of direct evidence of anything.

How many wet markets are in a city of 11 million people?

The seafood markets sell bats and other wild animals as well. When they butcher the bats, dogs eat the leftovers then someone else eats the dog. Plenty of ways for the virus to mutate.

probably wouldn't link to the daily mail tbh, they produce so much garbage it's impossible to just take any story they write at face value
