Lab leak hypothesis seems to cover a few possibilities:
Sars-CoV-2 originated in nature. A sample that was collected from a bat or other animal escaped from the lab.
Sars-CoV-2 was accidentally created in the lab via gain of function research.
The virus was intentionally created as a bioweapon.
To me, the argument for the first is that we have so many variants out there already. Nature is a damn fine engineer
But what exactly does a lab leak of a natural virus imply? It's not like the virus is King Kong, sitting there in chains. We have tons of MAGAts out there complaining about masks, that the likelihood of getting COVID is very small, etc.
If they had an aerosol can full of air with a bunch of COVID and sprayed it around outside the door of the lab, it's not like it would then be running wild.
Perhaps the hypothesis is that one of the researchers had it isolated, aerosolized it, infected him or herself, at which point the virus took hold in that person's body and they spread it, basically becoming patient zero?
