There’s an unnecessarily large assumption being made here. We can look at the Wuhan institute’s past and the history of comparable labs to get an estimation of lab leak frequency.
Similarly, there’s a whole bunch of context around things like: what kind of samples did the lab have in its freezers when covid was discovered? In the wetmarket case, what’s the transmission chain from a reservoir through to the market have to look like?
Once you compile all this context, then Occam’s Razor becomes a good tool. But before that it’s just a shot in the dark (kinda like you hint at). I’m not sure any single HN comment is really capable of giving sufficient context for this particular case.
