It's kinda obvious that the 'lab leak theory' was created just to attack China.
There are a lot of coincidences that make a lab leak a real possibility. It is possible those are all coincidences and the virus is of natural origin, but it is also possible that those are not coincidences and the virus originates from a lab leak.
Most likely we will never know since virus origin investigations are difficult to begin with, and China has no motivation to fairly cooperate in this investigation. It also is not actually important, since it is extremely unlikely the virus was intentionally released.
For political reasons it is better to go with the natural origin story and avoid stirring things up - there is no gain to be had from pressing the issue.
You say this as if you know that they're purposefully not being careful or something.
Looking at the article, it also uses weak arguments to support its thesis: "She first takes aim at the popular version of the lab leak theory that posits that Covid was taken from nature and escaped in its wild form. The problem with that scenario, she told me, is that a swab from a bat contains very little infectious virus. Each bat weighs less than half an ounce, and each sample is basically a Q-tip swiped briefly over a bat’s mouth or anus. These samples are stored in vials in the freezer; they’re not likely to spill or leak, the way disaster movies have primed us to suppose."
The real-world counter-argument to this is https://en.wikipedia.org/wiki/Marburg_virus
Lab leaks do happen, and all researchers in those labs do have an interest to play down the danger and cover things up to continue working.
It's not like ebola where single micro droplet is enough.
We know that they were doing gain of function research, but that only works with live viruses. So they must have some method to cultivate the virus. When they can do that small size of the initial sample is no longer relevant.
I have no time whatsoever for the nutters who say the lab leak is definitely correct or has been proven. Likewise I have no time for people who say the lab leak was not possible and should not be considered. In both cases there's a big chunk of motivated reasoning, and quite possibly wilful ignorance going on IMHO.
It was created because people thought it was weird that a novel bat coronavirus originated blocks away from a research facility specializing in novel bat coronaviruses.
