Assuming a zoonotic origin in China, it's much more likely that an infected individual from rural Southern China happened to travel to Wuhan and that the seafood market just happened to be the kind of location where such a virus would spread. There is some evidence that there is a degree of immunity to COVID-19 in areas that had SARS-outbreaks. It would therefore be plausible that an initial COVID-19 outbreak in Southern China, the epicenter of SARS1, could have gone unnoticed.
The actual animals sold at the market would then be irrelevant, but there's a narrative that "animal cruelty and human encroachment are to blame for COVID" that is being pushed here.
(1): I probably should use "unidentified", it was noticed that there was a unusual spike in pneumonia related death. It was just not linked to a "new" virus.
