My own experience: Don't ever trust the Chinese government on issues that could potentially involve the reputation of the party. Note that I'm not saying don't trust what CCP says, ever (sometimes they actually do good things) - just not on issues that involve anything to do with how the world might perceive them.
Which is exactly what this issue is about.
That's not to say we have compelling evidence that this was a lab virus, either. I think, for me, it's a, "we don't know, but I wouldn't be shocked at all if it was a lab virus".
"Lipsitch’s activists (calling themselves the Cambridge Working Group) sent around a strong statement on the perils of research with “Potential Pandemic Pathogens,” signed by more than a hundred scientists. The work might “trigger outbreaks that would be difficult or impossible to control,” the signers said. Fauci reconsidered, and the White House in 2014 announced that there would be a “pause” in the funding of new influenza, SARS, and MERS gain-of-function research." [0]
In December 2017, the US began funding gain-of-function research on these deadly diseases again. This research creates deadly diseases that may not have existed otherwise.
This pandemic has been enough for me to strongly believe that there should be a global ban on gain-of-function experiments on deadly viruses and bacteria. I'd like to help prevent a future pandemic, and that's one clear way we can help.

A failed experiment? Maybe a bit more likely, but still I don't think so
Sars-Cov-2 looks like pretty much what it is: a zoonotic virus that "doesn't know what's going on"
Hence why only the recent mutations made its transmission more efficient.
Now, if it escaped unbeknownst from a research lab, that I would put on the plausible category. Would be more possible if it wouldn't have had a perfect virus breeding ground right next to it.
