If you had told me scientists in the US would be able to send anthrax in the mail to members of the government, because they were pissed off with things, I'd have said "but that would never happen" -Except, it did kind of happen. Anthrax leaked out because somebody with access to secured disease facilities in the US, decided to do something. Something reprehensible, but they did.
So if you tell me its theoretically possible a gain-of-function experiment happened, And that all this behaviour from the Chinese government was after-the-fact fears about uncommanded, unacceptable risky behaviour in a lab, I maybe should be open to saying "ok: it is certainly possible people do bat shit crazy (hah) things"
I don't actually think a GOF experiment is at the root of this problem. I think its zoonotic, not manufactured, and I think seeking to write the lab into spread of a zoonotic disease is seeking to make political capital because of anti CCP feeling or trade wars.
Like diseases spread because farming and food practices are high risk for disease transmission. its sort-of Occams razor to say "it just happened" because we have good evidence it does just happen. Demanding this be seen as a smoking gun of human mediated lab-experimentation, I think is silly.
I would be asking Virologists and Geneticists: Does a Gain of Function experiment leave fingerprints in the DNA and RNA that we can track down?
As for your point about it being a trade-war tactic only goes so far when one realizes that Australia, which has China as its biggest trading partner, most vocally brought up the need for an investigation, and is being punished. Why would Australia start a trade war with its biggest customer?
Because we're politically native, and often misread the signals? Some of us believe it was a misguided attempt to curry favour in the US by bringing the US China dispute into Australia.
