I am looking for a single word that means to shun doing things for commercial purposes, or to shun trading for money. It can either be the act of so shunning or an instruction to so shun.
In context: I'm writing a story with a military group with a bunch of one-word-commands that encompass their ethical principles. They would have ceremonies where they assembled to receive officer training. And on each of (about) twelve posts there would be a single one-word instruction that captures a part of their ethics. It breaks up into 12 chapters where each principle is illustrated. So on the posts would be things like Honor, Loyalty, Prowess, Guile, and others.
The command to shun doing things for money is to keep them on the straight and narrow regarding motives. Doing things for cash all too easily leads to doing things for the enemy for cash. It's an idea at least as old as ancient Sparta, possibly considerably older.
The word Integrity almost captures it. If there is nothing better I can live with that.
