Back up a bit. What the fuck is "meta-scientific"?
Take your own theory and argument for it. You could only stare at a honest list of for and against regarding the lab leak, and conclude that lab leak is meta-scientific.
When you call for evidence, remember the information blackouts and destruction of samples ordered by the Chinese. Chinese citizens and scientists were dissapeared for following the science and doing proper journalism. To conclude their legacy as meta-scientific is ugly. That is not my science, but maybe that is your job here...
Metascientific means a scientific investigation into the practice of science. There is no value judgement there, it's a description of how the investigation is being conducted.
