An intentional lab leak makes no sense to me at all. Its like starting a fire in your house to spite your neighbour.
Very few people are arguing that it was intentional. I agree that an intentional lab leak is highly, highly unlikely, but I think an accidental lab leak is at least just as likely as the wet market hypothesis and CCP certainly acted extremely suspicious.
All major world governments do illegal and shady acts when faced with situations that may result in the need for extreme ass-covering. (cf. "righteous strike")
If it were an accidental lab leak: so what? How does that change things? If anything, it would accelerate a {trade,cold,cyber,shooting} war with China, which is universally a bad thing, even in pursuit of justice for something that was likely accidental (if indeed it came from a lab, which is presently undefined/unknown to the public).
> pursuit of justice
It has nothing to do with a pursuit of justice, at least not for me. It's about understanding where the disease came from and how it jumped to humans, so that we have a better shot at stopping something like this happening again.
That's a more important question about whether or not this particular virus came out of a lab or not, because, if the answer to the above is "yes", then we need to take whatever your/whoever's proposed mitigation/prevention steps even if this thing came about via natural pathways. Even banning GOF research in labs might not be sufficient, if malicious people (wooo "bioterrorism") could go about doing this outside of labs.
Also, we need to plan and prepare for the next global respiratory pandemic in any event, as we know they happen periodically regardless of origin. That's true even if we never authoritatively understand the origin of this one.
