Yes, I was among those who originally thought that the presence of the biolab in Wuhan was too significant to be a coincidence, but, in addition to the medical arguments you make, the fact that Xi focused on his economic model as he consolidated his control over the Chinese Communist Party over the last two years pretty much puts that theory to rest.
China has not only put its own economy into deep recession as a result of the virus, but the longer term impact will be to alter global trade patterns that have been evolving since the fall of the Soviet Union and lead to the "re-domestication" by the west of much of the supply chain that had migrated to China, India and elsewhere in Asia and the Subcontinent.
Nothing is impossible, but creating a virus this devastating without bulletproof safeguards to prevent its unintended release is just short of unfathomable.
