My question is, why? What does it matter whether the virus originated from a lab or from a wet market - it isn't any more dangerous if it came from a lab, nor does knowing the origin really help dealing with this crisis at all.
It is certainly interesting to know where it did originate, and that knowledge could inform a debate on the future of (respectively) wet markets and animal husbandry practices, or BSL facilities, but these don't strike me as particularly emotionally charged topics, and in any case the posts I'm referring to don't mention these debates...
Anybody care to explain why you would respond so strongly to claims of lab origin?
That being said, I tend to agree with your assertion.
There is also no need to ban such markets, but to further regulate what and how things can be sold is reasonable.
One problem often ignored is that because of differences in general wealth it's e.g. not always/every where feasible to require selling only pre-processed (cut apart) meat (and other body parts) as the necessary fridge infrastructure doesn't exist and would be to expansive.
