Believe whatever you want. If you believe the zoonotic origin, ok sure, but your circumstantial evidence for that is weaker than the circumstantial evidence for a lab leak.
Yes. You are supposed to believe the administration of a president when they claim: The virus came from China. Whether deliberate or accidental, it likely originated in a laboratory. If you don't, I reckon you have bigger problems than a pandemic. If you can't trust your government on such critical matters, if you really believe the US government would stand for the secretary of State spreading lies, then you should probably flee to China and ask asylum there.
> Sorry, but that's just not good enough.
But experts saying: "Virus is likely zoonotic, but we have no idea" is good enough? Again, demanding others to proof that a teacup is orbiting Venus is reasonable. But not when you can't even show the existence of teacups or Venus yourself.
> Actual evidence in the zoonotic origin column greatly surpasses that in the lab leak column.
There is no actual evidence. Actual evidence of zoonotic origin would establish the transmission chain and identify patient 0. There is none. You have "Bats can be the original carrier". So your hypothesis could be true. It is circumstantial. Any actual evidence would instantly kill one of the hypothesis. So you share some responsibility there.
For an example of how to turn the BBC article into circumstantial evidence for a lab leak, is to study the franticness that went on with sequencing and publishing. Wuhan lab published the sequencing of bats captured in 2017 in 2020. It was complete PR management campaign, with scientists blaming "Mother Nature" not their research, information black-outs, and sharing of "secret" sequences years after the fact in support of zoonotic chain, while blocking any outside investigation into the origin which would support/not support the zoonotic origin.
