@frphank imagine you are measuring your nephew’s height. He is a healthy young lad visibly progressing well.

Your ruler uses cm or inches - whatever your preference is.

All of a sudden the international society of ruler central planners decree that today’s cm/inches are 40% smaller than yesterday’s cm/inches.

Did your nephew grow 40% in height overnight?

This is fiat central planning in a nutshell. All economic calculation is persistently and periodically rugged.
