Remotely plausible that the virus was isolated and cultured in a lab for study from a host species but unrealistic that it arose as a result of some attempt to weaponize it, not in Wuhan anyway. Place is a dump.
Far more likely the virus leapt from a host species to human handlers (butchers) in one of the local 'wet markets' for animal/wildlife products that are endemic to the region and the nation as a whole. Colleague once said to me, "Only thing with four legs Chinese not eat is chair". And he was right - absolutely anything that slithers, burrows, flies, swims or crawls regularly ends up on someone's menu. And in Wuhan there are scores and perhaps hunderds of people working in street markets whose primary daily activity is a manic focus on capturing, killing, transporting and butchering bats, birds, wild (and domestic) mammals, insects, worms, rats, anything aquatic and in fact just about anything they can lay hands on. Historic function of trying to survive in a nation that now numbers 1.5 billion.
Many if not most of the Ebola outbreaks in Africa are a result of the 'bushmeat' trade. Several prominent infectious disease experts all but guaranteed that something like Covid would happen years ago, hardly the first time and won't be the last. Smallpox, chickenpox, AIDs, scarlet fever, rabies, Chlamydia, Salmonella, plague, H1N1 influenza, Lyme - all vectored by and/or originated in animals. Oops, time to feed the cat.
