The reason lab leak is considered a conspiracy theory, is because it's a literal conspiracy theory. The conspiracy being the CCP and potentially U.S. covering up a virus leak from their lab. Of course all sorts of other politics and disinformation get attached.
Nobody has the evidence necessary to make evidence based theories on lab leak. All we have is hand waving and "maybe".
Even if it did happen, what do you do? Sanction china? Tell them they were naughty? What this focus on lab leak without evidence does, is riles up the public, gets psuedo intellectual personalities in on the hand waving, and politics turns it into disinformation. The end result being anti-vaccine, anti-pharma, etc. Lab leak hypotheticals have so far done an incredible disservice.

Also will say the approach the conspiracy theorists and foreign policy operatives have taken with this isn't likely to garner any transparency from China going forward. That's bad because fundamentally despite differences the Chinese and the the US have common interests in this.
That seems to impliy that everyone who thinks the lab leak is possible also thinks it was intentional. Which I didn't see much of, in real life.
