There is possibly a form of survivorship bias here - it is likely that the WIV became the world leader in coronavirus research because it met the criteria for a BSL4 lab and is within a one to two day driving distance of places where previous coronavirus outbreaks started. In some ways it is unsurprising that it would be near the epicenter of an outbreak. I am not stating that it did not escape from the lab, just that there are additional factors to consider and the likelihood it was an escape is less obvious than you are making it out to be.
