Question time:

What makes you think that if people hoarding money is bad?
I agree that money is meant to be spent, but it should be spent wisely, without someone (the government) incentivizing us to spend. Scaring us with war and inflation or whatever else they can think of.
Ultimately money is your own. If I worked for it, I should be able to do whatever I want with it. You may not be aware of the fact that in many countries destroying money is a crime because it belongs to the government, not to you. You are only a user, borrowing it from the government to be able to transact, pretty much like you're not the owner of games you buy on Steam.
