To add to your point, it was a chain of improbable coincidences:
Pandemic starting at the doorstep of a lab (that is not located in remotely close proximity to the Yunnan caves where the previous SARS viruses were originating from)
Previous SARS virus outbreaks (SARS1 and MERS) had zoonotic reservoirs identified in months with dramatically fewer resources, but coincidentally, with vast resources and global efforts, no zoonotic reservoir identified for this virus.
Previous SARS virus outbreaks showed a gradual evolution of a virus to progressively becoming more infectious to humans, and equivalent genetic changes in the virus that can be traced. This one started out as highly infectious, and until several months in, mutations weren't very significant.
The Chinese Communist Party (not China, not the Chinese people, but the CCP) has expended far more energy suppressing research and scientific access than any form of investigation into the origins of the virus.
The CCP deliberately suppressed and arrested doctors publicly talking about the virus early on.
Edit:
Forgot to add that there is a direct paper trail (publicly available on data.gov) of grant documents which specify that the funding will be used in WIV for research of bat coronaviruses with (and I quote from the paper) "humanized mice". Humanized mice, in this context, are mice genetically engineered to have human ACE2 receptors lining their respiratory tissue. In what was the most infuriating moment of public testimony I have ever seen, Dr. Fauci argues that infecting humanized mice with animal viruses (resulting in animal viruses that can more easily infect humans) is NOT gain of function research. He was playing an obvious semantic game, where his definition of GOF is the far narrower concept of making an existing human infecting virus more infectious..... Seriously, I was a big fan of the guy until that single bit of testimony. Now i know he's a lying bureaucrat more than he is a scientist.
