Well, a lab breakout is just one possible vector of infection. The virus could have leaked into the wet market via other methods.
The fundamental flaws of a natural origin explanation are how the virus just emerged so well adapted to human biology and how no credible intermediate host has been identified.
Okay, tell me how it leaks into the market without infecting other humans and causing a lab outbreak (that would leave dozens hospitalized and some dead).
A pangolin runs into the laboratory, gets infected with a leaked virus, hops a dozen miles across the river to the marketplace, and infects everybody at the marketplace?
A broken water pipe floods the virus samples, carries the stored COVID virus down a drain and into river, travels up the sewage pipes, and infects everybody at the marketplace?
I'm happy to hear ideas, lol.
I've said it before, I've said it again. The fundamental flaw in the lab leak conspiracy theory is the lack of a lab outbreak.
