> You should also know that SARSCoV2 1) is not a chimeric virus,
There is no basis for this claim. Genomic evidence shows that SARS-CoV-2 is not a chimera of any two previously-known viruses. No possible genomic evidence could exclude a chimera of two previously-unknown viruses, and the WIV was the world's leading collector of such novel sarbecoviruses from nature. They proposed to make chimeras of them in DEFUSE. That proposal wasn't funded, but this article now reports explicit claims they did such work:

You're basically rehashing Andersen's "Proximal Origins" here, and even he has moved on to more sophisticated (though still unconvincing) arguments like Pekar. As David Relman wrote almost three years ago:
> This argument [that SARS-CoV-2 must be natural since it doesn't use a known backbone] fails to acknowledge the possibility that two or more as yet undisclosed ancestors (i.e., more proximal ancestors than RaTG13 and RmYN02) had already been discovered and were being studied in a laboratory—for example, one with the SARS-CoV-2 backbone and spike protein receptor-binding domain, and the other with the SARS-CoV-2 polybasic furin cleavage site. It would have been a logical next step to wonder about the properties of a recombinant virus and then create it in the laboratory.
