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.
