RaTG13 is a thousand mutations and several decades of evolution away from SARS-CoV-2, you don't get from having RaTG13 in a lab to SARS-CoV-2. There's no evidence that WIV recovered whole virus of RaTG13 or cultured it. SARS-CoV-2 is not a chimera of a RaTG13 backbone and an ACE2-attaching spike, there's a lot more mutations involved. You also don't get there from serial passage experiments in a lab, you need serial passage through decades and many millions of infections in nature, we can't operate at that scale.
