I'm absolutely not saying the origin doesn't matter for anything--if 2.9M people died due to a particular class of research, then that absolutely should affect our judgment as to whether that research should be funded or permitted (though that cost/benefit tradeoff seems grossly unfavorable to me regardless). The link between that question and China's perceived culpability just seems bizarrely overstated to me, divorced from the reality that the USA was entirely supportive of that research pre-pandemic.
So a lab leak, if true, would indeed significantly increase the number of lies being told.

I guess you could try counting up and comparing the total lies implied by each origin, but the volume is so high that seems pointless to me. Their strategy seems more like a general fog of confusion to me than a particular story intended to be believed.
