My conspiracy theory is that Covid-19 comes from a virus jointly engineered and unleashed by the Western and Chinese elites. This theory is supported by a combination of how unlikely the virus is to be natural (as detailed by Dr Li-Meng Yan's paper) and other attending events, including what strongly appears to be cover-up:

- The entire Western mainstream media and establishment set of virologists went out of their way to provide protection for, of all countries, China, which is  normally painted as a bad actor with every chance.

- The silencing of dissenting scientific voices.  Why not let the debate play out, if Dr Yan's argument or conspiracy theories have no merit.

- Somehow, early containment failed in all major Western economies and China, and these just happen to be the major sufferers of the debt bubble.  This happened when quite a few other countries have shown that early containment is possible.  As I've argued, it's not just Trump and his ilk who were responsible for the slow response.  The media and entire political class implicitly supported the do-nothing response, until it was too late.

- The suppression of HCQ+ as an excellent Covid treatment, even though this fact has been well documented around the world.  The media widely published 'studies' with flat-out fake data (for which major journals have retracted the publications, too late) that almost totally destroyed the image of HCQ+ among the public.  This is not to mention publicizing numerous studies on HCQ+ that were improperly done, some inexplicably so, that are negative about this treatment.

- The sudden appearance of a virus (RatG13) that was touted as a natural close relative of Sars-CoV-2 after theories of lab-made origin appeared.  RatG13 turned out, on close examination, to be most likely a lab creation, but one that was done too hastily to provide a believable evolutionary pathway.

- First and not least, the overwhelming incentives for the global elites to deflate the global debt bubble without taking the blame for the resulting pain.  In fact, in Sept. 2019, a fire erupted deep in core of the system (the repo market crisis.) Over the weeks and months, it could only be contained but somehow never put out, even with the supposed unlimited monetary powers of the Federal Reserve.  There's a good chance that the financial system's natural implosion had already started.

Perhaps, individually, these events could each be argued as happenstance, or what not.  But taken as a whole, they present a compelling set of evidence.
