So how would you measure the impact?
You don't want to measure it by looking at the increase in deaths.
You don't want to measure it by looking at hospital beds required.
You don't want to measure it by the number of positive tests (living or dead).
It seems like you just plain don't want to measure it and pretend it doesn't have big impact.
To the contrary, I would be fascinated by accurate data if it existed. There is no data that exists that has not been corrupted by financial incentives and politics.
