One thing, costed
Start with the number on the document
Every piece in this section begins with one concrete thing and asks what it actually costs. A ton-mile of freight. An acre-foot of Colorado River water. A kilowatt delivered to a data center. An ounce of gold in a central bank’s vault.
The method does not change. Find the primary document — the tariff, the statute, the rate schedule, the filing — and read the number off that rather than off somebody’s summary of it. Do the arithmetic where you can see it. Then ask the only question that makes the number interesting: why is it that number, and who decided?
The answers keep turning out to be about money, though rarely in the way the headline suggests. A posted water rate that has not moved since 2009 says more about price controls than any essay on inflation. What a central bank chooses to hold says more about trust than its statements do.
This is not a news feed and it is not a theory section. Halving House covers the foundations — what money is, how it loses value, who controls it. This section does the opposite trip: it starts at a receipt and works backward.

The Twenty-Dollar Acre-Foot
In 2026 the Imperial Irrigation District paid its growers $334 to leave an acre-foot of Colorado River water in the river. It charges those same growers $20 to deliver one. Both numbers are current. Neither is a typo. I spent a while assuming one of them had to be wrong, and the reason they can…

Where the numbers come from
Every figure is read off a document I opened, and the piece names that document and the date I read it. If a number is my own arithmetic rather than something published, it says so on the line that uses it.
When something could not be verified, it stays unverified in the text, with a note on what would settle it. Some of these end on an open question rather than a conclusion, because the record ran out.
