It's a fair point, and typical thinking, but wrong. Deflation is better than inflation.

First, in general asset inflation vs goods inflation is usually different. Then for goods inflation, there is no good measure. Substitute goods exist.

Asset inflation definitely improves lives of the rich. Your "hoarding scare" can happen when savings/bond rates are higher than inflation. That is the genuine hoarding motivation. Lower interest rates supported by deflation supports more borrowing for more production/housing, with lower financing costs passed on to consumers. Either way, all money in the banking/financial system is hoarded money, and fractional reserve lends more the more demand for money there is. Deflation is better than inflation for this.

For goods, electronics and now EVs are deflationary. Your phone from 2008 cost the same as one from this year while having 100x less power/apps/value. While it can make sense to wait on tech/value improvements, competition/innovation creates work, and the deflation is the cause of that innovation, and there is a replacement cycle. Energy, food, clothing deflation would allow for higher consumption and also more work, though rarely would there be expectation of continued sustained deflation. Deflation is always technology or imported/slave labour costs. Never domestic wage reductions, unless slavery pressures can be manifested. Tariffs can stop it though.

Any economic competition creates a deflationary pressure. Deflation can be renamed value enhancement. When you favour inflation over deflation you are saying, "scarcity good, competition bad, innovation bad"
