Hey man, no argument from me; I appreciate the need to study deadly diseases in the flesh. I just wonder if they could maybe locate their biosafety-level-4 lab somewhere other than in a metropolis of eleven million people. You know, just in case.
For what it's worth, one of the names on that paper is Shi Zhengli, one of the lab’s top researchers who is now defending the lab to the media:
[Shi Zhengli] said on her social media account that she “guaranteed with her own life” that the outbreak had nothing to do with the lab but was a “nemesis for the barbaric habits and lifestyle of some people – like eating wild game including bats.”

EDIT:
As I noted in my other comment, these researchers didn't actually create a new coronavirus, but rather a much simpler and safer virus purpose-built to test some receptor-binding structures.
