I'm not usually much of a conspiracy theorist, but this one seems plausible to me.

Summary

The website content discusses the plausibility of the theory that COVID-19 may have originated from a lab leak in Wuhan, China, due to the proximity of the outbreak to a lab with similar viral samples and the lack of a clear natural host.

Abstract

The author of the web content expresses a personal inclination towards the possibility that the COVID-19 pandemic could be traced back to a laboratory incident. This stance is based on several points: the genetic similarity of COVID-19 to viruses found in a Yunnan cave, the presence of these virus samples in a Wuhan lab, the unusual presence of a Furin site in the spike protein of the virus, and the significant genetic differences suggesting a gap in the natural evolution timeline. The author also notes the Wuhan lab's history of conducting gain of function research on chimeric coronaviruses, which could potentially create a virus like COVID-19. Despite these points, the author acknowledges the complexity of assigning blame due to international involvement in gain of function research funding.

Opinions

The author finds the lab leak theory plausible, especially given the lack of a definitive animal host for COVID-19.
The discovery of genetically similar viruses over a thousand miles away from Wuhan, yet in close proximity to the lab, raises suspicion about the lab's involvement.
The presence of a Furin site in the spike protein, which is considered unusual, adds to the speculation about the virus's origin.
The author points out that the genetic differences between COVID-19 and its closest known natural relative suggest a gap that cannot be accounted for by natural mutation rates over recent years.
The Wuhan lab's published research on creating chimeric coronaviruses is seen as a potential link to the virus's emergence.
The author questions the ethics and potential consequences of gain of function research and its international funding, complicating the issue of accountability.

I'm not usually much of a conspiracy theorist, but this one seems plausible to me.

When SARS was discovered, it was quickly linked to civet cats as the original host. We still haven't linked covid-19 to a host animal, other than some vague suggestions that it's some kind of bat/pangolin hybrid.

The closest genetic matches to covid-19 were discovered in a Yunnan cave, over a 1000 miles from Wuhan. Samples of those viruses were held in the lab. Seems more likely that samples got out, (with or without modification) than someone else coincidentally went to a Yunnan cave and then went to Wuhan and started an epidemic 10 miles away from the lab.

I've seen better analyses, like the unlikely addition of the Furin site in the spike protein. I'm not quite educated enough to understand all this.

You can easily say that the virus only mutates so fast (1-2 base pair mutations per week). If it's 92-96% similar to the closest natural virus, that's 20-40 years worth of mutations.

So we're missing the natural source. Or it's a chimera, a recombination of 2 viruses. That can happen in nature (i.e. in a pangolin that gets infected with 2 coronaviruses at once). But the Wuhan lab also did published work on gain of function research, making chimeric coronaviruses:

So... not a crazy idea at all.

I don't know how you would blame someone if this is all true. Does China pay for the global economic damage? As I understand it, the funding for gain of function research was international, so it might not be just China at fault.
