> 40,000 wet markets in China as of 2019

And yet it happened to spillover in a wet market in a city with the premier coronavirus research labs in the country. It also happened to happen far away from where these types of viruses originate. There are only a handful of labs in the county that do this type of research and WIV is the top one.

So why did not not appear in a wet market in Yunnan or Guangdong?

Guangdong was SARS-CoV-1.

We've had two spillovers now of sarbecoviruses and the first one hit a completely unrelated city. The other one happened in Wuhan, which is the biggest city in central China and its "catchement area" is probably fairly wide around it.

It does appear that they spillover in wet markets in big cities.

The level of coincidence here may look like rolling a 1d20 two times and the second time getting a natural 1.

Or a more related and much bigger coincidence: a man was killed by a nerve agent in what appeared to be a targeted attack on the home of a Russian defector approximately 10 miles from the UK's main lab studying nerve agents. Which is a similar distance between the Wuhan lab and wet market, though the UK version is a rural backwater rather than a major regional capital. Sometimes relative geographical proximity coincidences are just that. (if you think there's something to the geographic proximity of Porton Down to the Salisbury poisonings, you have to try to explain away an even more remarkable coincidence that two Russians protected by the Russian government took a very short holiday to 'see the cathedral' and somehow stumbled into the same boring suburb the nerve agent was left in on the same day. And the decision of presumed target Sergei Skripal to live there... )

Wuhan would look like less of a coincidence if it had been accompanied by a characteristic Chinese coverup "the researchers have retired and wish to spend their time not talking to the media" rather than something very uncharacteristic of a Chinese government coverup (scientific papers releasing data on origins which unconnected non-Chinese virologists and epidemiologists generally find credible) or if China had been way out ahead rather than miles behind in their vaccine efforts.

Lab leaks are enough of a known phenomenon not to be ruled out as wildly improbable, but the coincidence of the virus that leaks out of the Wuhan lab happening to be one they hadn't documented and happening to plausibly spread from an epicentre which contained the other most likely vector for the transmission of zoonotic viruses in Wuhan sounds... pretty much as big as the coincidence of a zoonotic virus being in the same major city as a lab for studying zoonotic transmissions of similar viruses prevalent in that large region.

That's a good one, I'm going to have to try to remember that.

Maybe because the lab is located where the virus is abundant?

But it's not, the head of the WIV even stated how unexpected it was for a SARS outbreak to happen in Wuhan and area not endemic to SARS like coronaviruses. If they wanted to be near the source they should have built it in Yunnan or even Guangdong where the last one broke out.

The lab is there for the same reason there are labs in Boston or NYC. Proximity to major research institutions
