==Money will become meaningless if you can't use to buy stuff.==

I don't follow this line of thought. We already give people money for not working (examples are social security and unemployment benefits). None of that has made money obsolete. Why would a temporary measure in the midst of a once-in-a-lifetime pandemic?

Why don't I see people make this same argument about businesses getting money from the government? Will money become meaningless for businesses? Do people stop trying to earn money once they reach a certain level? Elon Musk certainly hasn't.

Ok tell me then, let say the government give people money for not working then why would people then want to work on let say grocery store where you suggest its risky ?
