How to defend deflation when small Inflation is seen as good for investment and growth?

Hi fellow bitcoiners..How do you respond to the argument that a small level of inflation encourages consumption and investment? The idea is that cheaper financing provides incentives to invest, leading to positive trickledown effects for the economy as a whole.

How do you counter that claim that inflation is necessary for economic growth? Critics of deflation argue that people would delay big ticket purchases, expecting prices to drop, which could hurt industries. Is this really a realistic concern? Some people say Japan had deflation and that was problematic ? Didn't dig into that enough.
