Do we know the exact origins of every virus? Does it matter in the grand scheme? Perhaps it helps in developing treatments, but I would question what specific advantages you get knowing the exact origin of a mutating virus with multiple strains. I guess my point is that it seems like our time would be better spent developing treatments and protections against this and future pandemics instead.
Understanding the origin is the most critical piece of information to avoid future pandemics. Current data is inconclusive even for the most basic questions, such as the origin being natural or not, which very much matters, but investigation efforts are actively suppressed. Or at least I would think it matters, you and everyone else do not seem to care.
