The whole reason they were working with chimeras is that attempts to culture the virus for gain of function research failed. Using the unproven lab leak origin theory to put a stop to research that wasn't actually being done is not reasonable or logical.
That is a really uncharitable reading of what I said. I don't know the details of what they were researching, I am not an expert. I'm just saying, the scenario that it could have been a lab leak, or that there could be a lab leak in future, should be taken more seriously. I don't know if they did GOF experiments (and I'm sure the pop-sci image of monkeys in cages a few feet apart is probably wrong). But we should think of regulating more strictly whatever they did (or didn't) do that could cause such an outbreak.
