So if I take a truckload of 100$ bills, a bottle of gin and a can of gasoline, drive into the dessert, out of sight of the authorities, and burn the entire lot, then the next night all retailers will have a vision which tells them to lower their average prices by 0.573%?

It's a hypothetical point; a small reduction in money supply will affect prices far less than the uncertainty or random fluctuation in the measurement of prices.

Is this comment sarcastic? I can't tell.

The money supply affects prices. It's basic econ.

How fast does a change made by a private actor to the money supply propagate? Surely not instantaneously?

By the time you fill your truck with those $100 bills, the prices will have already adjusted. If you decide to not burn them, but spend them quickly, the prices will adjust again.

> causing a small amount of destruction to something that other people value.

Yea, like the environment.
