the fact that this theory is still around after more than a year and not completely debunked is quite telling by itself. I thought this was a complete conspiracy theory last year, but the longer it sticks around the more likely it does become.

Debunking a theory doesn't make it disappear. Sometime it can do the opposite and reinforce the theory.

In this case there is no smoking gun either way and a natural origin is much harder to trace than lab origin. That lack of absolute certainty, which science is often comfortable working with, leaves room for alternative theories to circulate and attach to those who like the sound of them for various reasons. It is a common human flaw that being aware that an event could hypothetically occur can be mistaken for proof that event actually occurred.
