Uhm, the Spanish flu infected 500 million people (6.5 times more than covid19) and killed about 50 million (33 times more than covid19). And if you consider that the world at that time had just about 2 billion people, a modern Spanish flu would have killed 175 million people (100 times more than covid19), and probably more since denser population makes it easier for viruses to spread.

Now, we have the (repeatedly) proven ability to avoid such a disaster, and you argue we should not? You really think protection from disease is not a basic human right?
