Maybe it's the other way around. They put the lab in Wuhan because it's easy to get many samples of the zoonotic viruses of concern due to the presence of many natural reservoirs and wet markets, and you want a lab near the action because you want to be able to study the hot spots.
In other words, your argument is like saying occam's razor concludes that fire extinguishers start fires because they are always found in the vicinity of fires.
Also I think many on this thread greatly underestimate the adaptive and evolutionary capabilities of nature. Having done some wet lab myself, I'm impressed at the ability of nature to do lateral gene transfer, and also it's damn hard to make any experiments work. Plus there are multiple layers of safety and containment around any lab experiment. Movies make engineering look like AI robots in labs and biology experiments that work on the first try, and people who say lab near outbreak must implicate the lab have probably spent more time watching movies about outbreaks than trying to engineer organisms themselves. Having spent a lot of time trying and failing to engineer organisms, occam's razor screams to me that the most likely explanation is natural evolution.
The real lab of concern are the hundreds of millions of people living in close contact with animal reservoirs, performing millions of competitive, uncontrolled evolution experiments daily, with single hosts sometimes simultaneously infected by multiple viruses, thus facilitating lateral gene transfer... and this continues to be the status quo. If you can accept that MERS and SARS CoV-1 are naturally evolved, then occam's razor would indicate that SARS CoV-2 is just one point in a series, and yet another coronavirus outbreak is likely to emerge in the next decade or so, from a dense urban area near animal reservoirs.
Distracting ourselves by fantasizing that only humans could be so devious to create such a virus makes us miss a very important opportunity to try and prevent the next outbreak through careful monitoring and research.
So, if you believe that we should have fire departments and fire extinguishers near ignition sources then, maybe we should have /more/ labs like Wuhan's in high risk areas, not less. And we'd want to encourage more cross border cooperation, not antagonize it, because viruses don't give a damn about your politics.
It's concerning that threads like this, on a forum as ostensibly pro-science as HN, are pushing ourselves further away from science and transparency...
