It's important that information be able to be shared freely, and dissenting opinions be able to be expressed without fear or repercussions.
People who said this came from a lab, or even said COULD have come from a lab etc were deplatformed, demonitized, berated, called conspiracy theorist, etc. From people with major platforms to the average American, anyone who dared challenge the approved narrative faced consequences.
The lasting lesson from Covid CAN NOT be the government is never wrong, the experts are never wrong, and no matter what your qualifications are you are not permitted to have any opinions or ideas outside the approved talking points.
As far as what happens if it was proven one way or the other, let's say it was a lab creation, what steps are we taking to prevent something like this happening again? If it came from a bat, well that's just bad Wuhan luck and not much we can do except to convince chinese people not to eat bats...But if it came from a lab, now we need to determine how, and if there was negligence or poor process that allowed it to escape...
So yes, it matters.
