Again, it’s not impossible or even implausible that the spread could have happened like that, or that there were cases elsewhere that went unrecognized. But that’s not nearly the same as flippantly describing this as the lab just “down the street” from the market.

The possibility hasn’t been incontrovertibly ruled out (and maybe never can be at this point), and it’s important to do independent investigations and examine the lab’s research, etc. It’s just not considered by most experts to be the most likely possibility.

As a geographical comparison, it would be like having a new disease outbreak where all of the known cases for the first several weeks were in Brooklyn, NY and concluding that the source could have been a lab in Newark, NJ. It’s possible, but not the first place to look.
