Taking masks as an example, how much stockpiling is enough? China has a population of 14, and a stockpile of 1.4 billion masks is not enough for one day. Then stockpile a few times more and you can use them for a few more days. That's right. But where does the money come from?
Of course, you're talking about more than just masks, such as extermination supplies, protective clothing, medicines and so on. The amount of money these cost would be quite large.
China has a lot more to do than just stockpile masks.
Two, the stockpile of supplies has a shelf life
Everything I just said, medicines, antiseptic supplies, masks, etc., have a shelf life. There is an epidemic, used. If there's no epidemic, the extra stockpile can't be used, it can only be thrown away, so each country won't stockpile such a large amount.
The U.S. epidemic came, too, ah, the country has only 30 million masks, they are too large a gap.
Trying to make it up right away, sorry, no one can produce that many masks at once.
So, just from these two points, you can see that the stockpile of supplies, there should be a scientific amount, not unlimited stockpile
