It is common sense, or it makes sense.
On a side note, I think that what you are saying is the main fault of a deflationary currency. Everyone hoards and never spends = no economy
I'm aware that many economists think deflation is bad because of that. But here's what I always respond:
You say nobody want's to buy due to deflation because price will be cheaper tomorrow. I say with the same logic nobody should want to sell due to inflation because price will be higher tomorrow. Yet people are selling things all the time. People are also buying massive amounts of phones and computers, even though they will be better tomorrow. In real life, very few people can afford to hoard and wait. We have needs as humans that can't be put on hold forever.
I do believe some
unnecessary consumption might be cut, but some might argue that is exactly what our planet needs in order to better maintain the rising population.
